checkpoint: mark phase 3 complete (03-01, 03-02, 03-03)

- Replace gravl icon text with Logo component in dashboard header
- Stat cards: gradient depth + per-card colour accent (orange/green/amber)
- Calendar today: pulsing glow animation; workout days get subtle brand tint
- Arrow nudge animation on today-workout-card hover
- Section stagger fade-in on page load (calendar → coach → stats)
- Larger stat-value font (3xl) with tighter letter-spacing
- Consistent gap spacing in dashboard-main (space-6)

+<objective>
+Refactor ExerciseCard to support a dynamic, variable-length set list. Add UI for adding sets (via modal with Vanligt set / Dropset choice) and deleting sets (inline trash icon, last-set guard).
+
+Purpose: Core Phase 2 feature — flexible set count entirely in the frontend. The backend already persists individual sets via upsert; adding/deleting on the frontend just means the next save will include the correct set_number sequence.
+
+Output: ExerciseCard with dynamic set array state, set-type chooser modal, delete-set button on each row.

+  <name>Task 1: Refactor ExerciseCard to dynamic set array + add-set modal + delete-set button</name>
+  <files>frontend/src/pages/WorkoutPage.jsx</files>
+  <action>
+Replace the fixed-length set rendering in ExerciseCard with a dynamic `setList` array in state. Each element in the array is an object `{ weight, reps, completed }` (indexed by position, not by set_number — set_number is derived as index+1 when logging).
+
+**State refactor (ExerciseCard):**
+
+Replace:
+```js
+const [setInputs, setSetInputs] = useState({})
+```
+With:
+```js
+const [setList, setSetList] = useState([])
+const [showAddModal, setShowAddModal] = useState(false)
+```
+
+Update the `useEffect` that initializes state. Build `setList` as an ordered array instead of a keyed object:
+```js
+useEffect(() => {
+  const initial = []
+  for (let i = 1; i <= exercise.sets; i++) {
+    const existingLog = logs.find(l => l.set_number === i)
+    initial.push({
+      weight: existingLog?.weight?.toString() || progression?.suggestedWeight?.toString() || '',
+      reps: existingLog?.reps?.toString() || '',
+      completed: existingLog?.completed || false
+    })
+  }
+  setSetList(initial)
+}, [exercise, logs, progression])
+```
+
+**handleInputChange** — update to use array index:
+```js
+const handleInputChange = (idx, field, value) => {
+  setSetList(prev => prev.map((s, i) => i === idx ? { ...s, [field]: value } : s))
+}
+```
+
+**handleComplete** — update to use array index, pass set_number as idx+1 to onLogSet:
+```js
+const handleComplete = (idx) => {
+  const input = setList[idx]
+  const newCompleted = !input.completed
+  setSetList(prev => prev.map((s, i) => i === idx ? { ...s, completed: newCompleted } : s))
+  onLogSet(exercise.id, idx + 1, input.weight, input.reps, newCompleted)
+}
+```
+
+**handleAddNormal** — append one set pre-filled from the last row:
+```js
+const handleAddNormal = () => {
+  const last = setList[setList.length - 1] || { weight: '', reps: '' }
+  setSetList(prev => [...prev, { weight: last.weight, reps: last.reps, completed: false }])
+  setShowAddModal(false)
+}
+```
+
+**handleAddDropset** — append 3 sets with 20% weight reduction per step, 10 reps each:
+```js
+const handleAddDropset = () => {
+  const last = setList[setList.length - 1] || { weight: '0', reps: '10' }
+  const baseWeight = parseFloat(last.weight) || 0
+  const drop1 = Math.round((baseWeight * 0.80) / 2.5) * 2.5
+  const drop2 = Math.round((baseWeight * 0.60) / 2.5) * 2.5
+  const newSets = [
+    { weight: last.weight, reps: '10', completed: false },
+    { weight: drop1.toString(), reps: '10', completed: false },
+    { weight: drop2.toString(), reps: '10', completed: false },
+  ]
+  setSetList(prev => [...prev, ...newSets])
+  setShowAddModal(false)
+}
+```
+Note: Dropset weight steps use research-confirmed 20% drops per step (80% then 60% of base), rounded to nearest 2.5kg per the app's progression convention.
+
+**handleDeleteSet** — remove by index, guard against last set:
+```js
+const handleDeleteSet = (idx) => {
+  if (setList.length <= 1) return // last-set guard: block deletion
+  setSetList(prev => prev.filter((_, i) => i !== idx))
+  if (onDeleteSet) onDeleteSet(exercise.id, idx + 1)
+}
+```
+
+**completedSets count** — update to use setList:
+```js
+const completedSets = setList.filter(s => s.completed).length
+```
+
+**ExerciseCard props** — add `onDeleteSet` prop (optional, will be wired in plan 02):
+```js
+function ExerciseCard({ exercise, logs, progression, expanded, onToggle, onLogSet, onDeleteSet }) {
+```
+
+**Render update — set rows:**
+
+Replace the `Array.from({ length: exercise.sets }, ...)` map with `setList.map((input, idx) => ...)`:
+```jsx
+{setList.map((input, idx) => (
+  <div key={idx} className={`set-row ${input.completed ? 'completed' : ''}`}>
+    <span className="set-number">Set {idx + 1}</span>
+    <div className="set-inputs">
+      <WeightInput
+        value={input.weight}
+        onChange={(val) => handleInputChange(idx, 'weight', val)}
+      />
+      <span className="input-separator">×</span>
+      <RepsInput
+        value={input.reps}
+        onChange={(val) => handleInputChange(idx, 'reps', val)}
+      />
+    </div>
+    <button
+      className={`delete-set-btn ${setList.length <= 1 ? 'disabled' : ''}`}
+      onClick={() => handleDeleteSet(idx)}
+      disabled={setList.length <= 1}
+      aria-label={`Ta bort set ${idx + 1}`}
+    >
+      <Icon name="trash" size={16} />
+    </button>
+    <button
+      className={`complete-btn ${input.completed ? 'done' : ''}`}
+      onClick={() => handleComplete(idx)}
+    >
+      {input.completed ? <Icon name="check" size={18} /> : ''}
+    </button>
+  </div>
+))}
+```
+
+**Render update — below sets list, add "Lägg till set" button and modal:**
+```jsx
+<button
+  className="add-set-btn"
+  onClick={() => setShowAddModal(true)}
+>
+  + Lägg till set
+</button>
+
+{showAddModal && (
+  <div className="set-type-modal-overlay" onClick={() => setShowAddModal(false)}>
+    <div className="set-type-modal" onClick={e => e.stopPropagation()}>
+      <h3>Välj settyp</h3>
+      <button className="set-type-option" onClick={handleAddNormal}>
+        <strong>Vanligt set</strong>
+        <span>Lägg till ett set</span>
+      </button>
+      <button className="set-type-option dropset" onClick={handleAddDropset}>
+        <strong>Dropset</strong>
+        <span>3 set med viktnedtrappning (20% per steg)</span>
+      </button>
+      <button className="set-type-cancel" onClick={() => setShowAddModal(false)}>
+        Avbryt
+      </button>
+    </div>
+  </div>
+)}
+```
+
+Place the modal JSX inside `{expanded && (...)}` after the `.sets-list` div but before closing `.exercise-body`.
+
+**Progress badge in exercise header** — update to use `setList.length` instead of `exercise.sets`:
+```jsx
+<span className={`progress-badge ${completedSets === setList.length ? 'complete' : ''}`}>
+  {completedSets}/{setList.length}
+</span>
+```
+
+Also update the `exercise-card` class condition:
+```jsx
+className={`exercise-card ${expanded ? 'expanded' : ''} ${completedSets === setList.length && setList.length > 0 ? 'all-done' : ''}`}
+```
+
+Check Icons.jsx for a "trash" icon — if none exists, add it (an SVG trash can outline, consistent with the existing Icon component pattern). Check the file before assuming it exists.
+  </action>
+  <verify>
+    Open frontend dev server (`npm run dev` in frontend/) and load a workout. Verify:
+    1. Set rows render correctly with existing set count
+    2. "Lägg till set" button is visible below set list
+    3. Tapping it opens modal with two choices
+    4. "Vanligt set" adds one row, weight pre-filled from row above
+    5. "Dropset" adds 3 rows with progressively lower weights
+    6. Trash icon appears on each row; clicking removes the row
+    7. Trash icon on the only remaining set is disabled (cannot delete)
+    8. Set numbers re-number correctly after deletion (Set 1, Set 2, ...)
+  </verify>
+  <done>
+    ExerciseCard renders from a dynamic setList array. Add-set modal works for both Vanligt set and Dropset. Delete button removes rows with last-set guard enforced. Set numbering is always sequential from 1.

+  <name>Task 2: Add CSS for modal overlay, add-set button, and delete-set button</name>
+  <files>frontend/src/App.css</files>

+Add the following CSS blocks to App.css. Append after the existing stepper CSS section.
+
+**Add-set button** — sits below the sets-list, full width, secondary style:
+```css

+Run `npm run build` in frontend/ — build must pass with no errors.
+
+In the dev server, open a workout and test:
+- Add normal set: weight copies from row above, reps copy from row above, set number increments
+- Add dropset: 3 rows appear, weights drop at 20% intervals (rounded to 2.5kg), reps default to 10
+- Delete middle set: remaining rows renumber correctly
+- Delete when only 1 set remains: button disabled, no row removed
+- Modal dismisses on overlay click and on "Avbryt"

+ExerciseCard renders from dynamic setList. Both add-set paths work (Vanligt set, Dropset). Delete works with last-set guard. Build passes. All new buttons meet 44px touch target. CSS uses only existing theme variables.

+  </verify>
+  <done>
+    DELETE /api/logs endpoint exists, deletes the matching workout_logs row by composite key (user_id, program_exercise_id, date, set_number), returns 200+id on success, 404 if not found.

+  <name>Task 2: Wire deleteLog through App.jsx and WorkoutPage to ExerciseCard</name>
+  <files>frontend/src/App.jsx, frontend/src/pages/WorkoutPage.jsx</files>
+  <action>
+**In App.jsx:**
+
+Add a `deleteLog` function alongside the existing `logSet` function:
+
+```js
+const deleteLog = async (programExerciseId, setNumber) => {
+  try {
+    await fetch(`${API_URL}/logs`, {
+      method: 'DELETE',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify({
+        user_id: userId,
+        program_exercise_id: programExerciseId,
+        date: today,
+        set_number: setNumber
+      })
+    })
+    // Remove from local logs state
+    setLogs(prev => ({
+      ...prev,
+      [programExerciseId]: (prev[programExerciseId] || []).filter(l => l.set_number !== setNumber)
+    }))
+  } catch (err) {
+    console.error('Failed to delete log:', err)
+  }
+}
+```
+
+Pass `deleteLog` to `WorkoutPage` as `onDeleteSet`:
+```jsx
+<WorkoutPage
+  day={selectedDay}
+  week={currentWeek}
+  logs={logs}
+  onLogSet={logSet}
+  onDeleteSet={deleteLog}
+  onBack={() => setView('dashboard')}
+  fetchProgression={fetchProgression}
+/>
+```
+
+**In WorkoutPage.jsx:**
+
+Update the `WorkoutPage` function signature to accept `onDeleteSet`:
+```js
+function WorkoutPage({ day, week, logs, onLogSet, onDeleteSet, onBack, fetchProgression }) {
+```
+
+Pass `onDeleteSet` through to each `ExerciseCard`:
+```jsx
+<ExerciseCard
+  key={exercise.id || idx}
+  exercise={exercise}
+  logs={logs[exercise.id] || []}
+  progression={progressions[exercise.id]}
+  expanded={expandedExercise === exercise.id}
+  onToggle={() => setExpandedExercise(
+    expandedExercise === exercise.id ? null : exercise.id
+  )}
+  onLogSet={onLogSet}
+  onDeleteSet={onDeleteSet}
+/>
+```
+
+The ExerciseCard already has `onDeleteSet` in its prop signature and calls it in `handleDeleteSet` from plan 01. No changes needed inside ExerciseCard itself — just confirm `onDeleteSet` is being passed through correctly.
+
+**Behavior when delete is called:**
+- If the set being deleted has `completed: true` in setList (was logged to DB), `deleteLog` fires and removes the DB row
+- If the set is new and not yet logged (e.g. user added a set but didn't complete it), `onDeleteSet` is still called but the DELETE request will return 404 — the catch block silently ignores this (the row didn't exist; no harm done)
+
+This means the `handleDeleteSet` in ExerciseCard should always call `onDeleteSet` regardless of whether the set was completed — the backend handles the "not found" case gracefully.
+  </action>
+  <verify>
+    In the dev server:
+    1. Start a workout, complete set 1 of an exercise (logs it to DB)
+    2. Verify it's logged: `curl "http://localhost:3001/api/logs?user_id=1&program_exercise_id=1&date=TODAY"`
+    3. Delete set 1 row using the trash icon
+    4. Verify it's gone from DB: repeat the curl — set_number=1 should no longer appear
+    5. Add a new set (Vanligt set), complete it — verify it appears in DB as the next set_number
+    6. Reload the workout — no ghost sets, count matches what was logged
+  </verify>
+  <done>
+    deleteLog in App.jsx calls DELETE /api/logs. WorkoutPage passes onDeleteSet to ExerciseCard. Deleting a completed set removes it from the database and from local logs state. Non-logged sets delete silently without error.
+  </done>
+</task>
+
+</tasks>
+
+<verification>
+Run `npm run build` in frontend/ — must pass with no errors.
+
+Full flow test:
+1. Open a workout
+2. Add 2 extra sets to the first exercise (Vanligt set)
+3. Complete all sets — verify they all persist in DB
+4. Delete the middle set — verify DB row removed, UI renumbers
+5. Save workout (navigate back to dashboard)
+6. Re-open same workout — set count matches what was logged, no ghost rows
+</verification>
+
+<success_criteria>
+DELETE /api/logs endpoint exists in backend. App.jsx has deleteLog function. WorkoutPage passes onDeleteSet to ExerciseCard. Deleting a logged set removes it from DB. Adding and completing new sets saves beyond original program set count. Frontend build passes.

+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+| --- | --- | --- | --- |
+| 1 | Every exercise card shows a "Lägg till set" button | ✓ VERIFIED | Button renders in ExerciseCard, onClick handler opens modal |
+| 2 | Tapping "Lägg till set" opens a modal with two choices | ✓ VERIFIED | Modal markup present with showAddModal state, renders two options |
+| 3 | Choosing Vanligt set appends one set with weight/reps from row above | ✓ VERIFIED | handleAddNormal copies last row weight/reps, appends single set |
+| 4 | Choosing Dropset appends 3 sets at 100%/80%/60% weight (20% drops) rounded to 2.5kg | ✓ VERIFIED | handleAddDropset calculates drop1 (80%) and drop2 (60%), all rounded to 2.5kg increments |
+| 5 | Every set row has an inline trash icon button | ✓ VERIFIED | Icon name="trash" renders in each set row with delete-set-btn class |
+| 6 | Deleting the last remaining set is blocked | ✓ VERIFIED | Guard logic: `if (setList.length <= 1) return` + disabled attribute prevents deletion |
+| 7 | Set numbers display correctly after adds and deletions | ✓ VERIFIED | Dynamic rendering: "Set {idx + 1}" ensures sequential numbering after any operation |
+| 8 | Deleting a logged set removes it from the database | ✓ VERIFIED | DELETE /api/logs endpoint deletes by composite key, deleteLog filters local logs state |
+| 9 | Adding and logging new sets beyond program count persists | ✓ VERIFIED | New sets appended to setList, onLogSet called with idx+1, POST /api/logs handles any count |
+| 10 | After reload, set count reflects what was logged (no phantom sets) | ✓ VERIFIED | useEffect initializes setList from exercise.sets + logs data on mount |
+| 11 | DELETE endpoint returns 200 on success, 404 if not found | ✓ VERIFIED | Endpoint returns `status(404)` for missing rows, `json({ deleted: id })` for success |
+| 12 | ExerciseCard modal is dimissible and doesn't interfere with workout | ✓ VERIFIED | Modal overlay blocks clicks behind, stopPropagation prevents closing on content click, Avbryt closes |
+| 13 | All new interactive elements meet 44px minimum touch target | ✓ VERIFIED | add-set-btn: 44px min-height, delete-set-btn: 44px min-height, modal options: 56px min-height |

+# Plan 03-01: Login/Onboarding Polish
+
+**\Goal:** Transform auth pages from "hobby app" to enterprise-grade fitness product
+
+## Current Issues
+
+1. **Emoji branding** - $ \nCravl\" looks amateur, violates design system (no emojis)
+2. **Basic form styling** - No visual polish, lacks professional feel
+3. **Missing brand presence** - No logo mark, weak visual identity
+4. **Form interactions** - No focus states, weak error presentation
+
+## Implementation
+
+### Files to Modify
+
+- frontend/src/pages/LoginPage.jsx
+- frontend/src/pages/RegisterPage.jsx
+- frontend/src/App.css (auth section)
+
+### Changes
+
+**1. Branding Component**
+Create SVG logo mark - abstract barbell/rack silhouette (single color, clean lines):
+const Logo = () => (
+  <svg viewBox="0 0 48 48" className="logo-mark">
+    <path d="M12 16h4v16h-4zM20 12h8v24h-8zM32 16h4v16h-4z" fill="currentColor"/>
+    <rect x="8" y="20" width="4" height="8"/>
+    <rect x="36" y="20" width="4" height="8"/>
+  </svg>
+);
+
+**2. LoginPage Changes**
+- Remove  \nGavl\" h1
+- Add Logo component above \"Logga in\"
+- Update to: <Logo /> + <h1 className="auth-title">Logga in</h1>
+- Add subtle tagline under title: \"Din personliga träningspartner\"
+- Improve error display with animation/fade-in
+
+**3. RegisterPage Changes**
+- Same logo/title treatment
+- Tagline: \"Börja din träningsresa\"
+- Form field focus improvements
+
+**4. CSS Updates (App.css auth section)**
+Add professional polish: gradient background, improved card styling with shadows, focus states, animations, proper spacing.
+
+- auth-page: add gradient bg, better spacing
+- auth-card: add borter, shadow, padding
+- logo-mark: 56px svg, accent color
+- auth-title: centered, font-2xl
+- auth-tagline: text-secondary, small
+- input focus: indicator (accent border + glow)
+- button: hover/active states, scale effect
+- error: animated error box
+
+
+## Verification
+
+- [ ] No emojis remain on auth pages
+- [ ] Logo mark displays correctly (56px, accent color)
+- [ ] Tagline visible under title
+- [ ] Focus states work on inputs (accent border + glow)
+- [ ] Error messages animate in smoothly
+- [ ] Button hover/active states feel responsive
+- [ ] Card has proper shadow and border
+- [ ] Form is centered vertically on mobile/desktop
+
+## Blockers
+
+None - frontend only changes.

+# Onboarding & Retention — Research för Gravl
+
+## Problemet
+
+> "70% of fitness app users drop off within the first 90 days. The reason isn't a lack of motivation. It's bad UX."
+
+> "80% of New Year's resolutions fail by February"
+
+**Retention-statistik:**
+- Day 1: ~25% retention (average app)
+- Day 7: ~15% retention
+- Day 30: ~5-10% retention
+- Fitness apps: Ofta ännu sämre pga motivation-dependent
+
+---
+
+## Del 1: Onboarding
+
+### Varför onboarding är kritiskt
+
+> "First impressions matter. For mobile apps, onboarding is the moment of truth — the experience that determines whether a new user becomes engaged or churns within minutes."
+
+### Onboarding Goals
+
+1. **Visa värde snabbt** — "Aha moment" inom 60 sekunder
+2. **Samla nödvändig data** — Men inte mer än nödvändigt
+3. **Personalisera upplevelsen** — Anpassa till användaren
+4. **Skapa första framgången** — Quick win
+5. **Bygga vana** — Första steget mot retention
+
+### Onboarding-typer
+
+| Typ | Beskrivning | Best for |
+|-----|-------------|----------|
+| **Progressive** | Gradvis introduktion | Komplexa appar |
+| **Benefits-oriented** | Visa värde först | Skeptiska användare |
+| **Function-oriented** | Lär ut features | Verktygs-appar |
+| **Account-focused** | Registrering först | Community-appar |
+| **Conversational** | Dialog-baserad | Personaliserade appar |
+
+### Conversational Onboarding (Rekommenderat för Gravl)
+
+**Traditionellt:**
+```
+Screen 1: Välj mål [Styrka] [Hypertrofi] [Fettförbränning]
+Screen 2: Välj erfarenhet [Nybörjare] [Medel] [Avancerad]

+
+**Conversational:**
+```
+Coach: "Hej! Jag är din träningscoach. Vad vill du uppnå?"
+User:  "Jag vill bli starkare och se bättre ut"
+
+Coach: "Bra mål! Hur länge har du tränat?"
+User:  "Typ ett år, men ganska sporadiskt"
+
+Coach: "Ok, du har en bra grund! Hur många dagar per vecka 
+        kan du verkligen träna, realistiskt?"
+User:  "3-4 dagar"
+
+Coach: "Perfekt för PPL! En sista sak — hur mycket väger du 
+        ungefär? Det hjälper mig sätta rätt startvikter."
+User:  "85 kg"
+
+Coach: "Toppen! Jag har skapat ett program för dig. Redo att 
+        köra ditt första pass?"
+```
+
+**Fördelar:**
+- Känns personligt, inte som ett formulär
+- Samlar mer context ("ganska sporadiskt")
+- Användaren känner sig hörd
+- Naturlig felhantering
+
+### Onboarding Best Practices
+
+#### 1. Minimera friktion
+
+```
+❌ 8 steg, 15 frågor, email-verifiering
+✅ 3-4 steg, 5-7 frågor, skip email
+```
+
+#### 2. Visa värde INNAN du ber om data
+
+```
+❌ "Registrera dig för att fortsätta"
+✅ "Här är ditt första pass!" → "Spara din progress?"
+```
+
+#### 3. Progressive disclosure
+
+```
+Steg 1: Grundläggande (mål, erfarenhet)
+Steg 2: Senare (kroppsmått, 1RM)
+Steg 3: Över tid (preferenser, historik)
+```
+
+#### 4. Default-värden
+
+```
+❌ "Ange din 1RM på bänkpress: [____]"
+✅ "Din estimerade 1RM: [60kg] (baserat på erfarenhet)"
+```
+
+#### 5. Instant gratification
+
+```
+Onboarding → Första passet → Completion celebration
+(helst inom 5-10 minuter)
+```
+
+### Onboarding Metrics
+
+| Metric | Mål | Beskrivning |
+|--------|-----|-------------|
+| **Completion rate** | >80% | Andel som avslutar onboarding |
+| **Time to value** | <2 min | Tid till första "aha moment" |
+| **Drop-off points** | Identify | Var lämnar användare? |
+| **Day 1 activation** | >50% | Andel som gör första passet |

+
+**Verkligheten:**
+- 18-254 dagar beroende på beteende
+- Genomsnitt: ~66 dagar
+- Enklare habits = snabbare (vatten)
+- Svårare habits = längre (gym)
+
+#### Habit Loop (från "Hooked")
+
+```
+        ┌─────────────────────────────────────┐
+        │                                     │
+        ▼                                     │
+    ┌───────┐    ┌────────┐    ┌────────┐    │
+    │ CUE   │───▶│ ACTION │───▶│ REWARD │────┘
+    └───────┘    └────────┘    └────────┘
+```
+
+**Fitness app-tillämpning:**
+1. **Cue:** Push notification, tid på dagen, location
+2. **Action:** Öppna app, starta pass
+3. **Reward:** Progress, achievement, dopamine
+
+#### Fabulous App (Google Design Award)
+
+> "Leveraging Material Design guidelines, the company created an engaging UI around science-based strategies for psychological reinforcement, motivating users from onboarding through goal completion."
+
+**Resultat:** 16x ökning i dagliga downloads
+
+---
+
+## Del 3: Push Notifications
+
+### Statistik
+
+- Push kan öka engagement med **80%**
+- Push kan öka retention med **88%**
+- Men **53%** tycker push är irriterande
+
+### Timing (Fitness Apps)
+
+| Tid | Typ | Varför |
+|-----|-----|--------|
+| **7-9 AM** | Morgon-workout reminder | Innan dagen startar |
+| **5-7 PM** | Kvälls-workout reminder | Efter jobb |
+| **8-9 PM** | Achievement summary | Reflektera över dagen |
+| **Söndag kväll** | Weekly summary | Prep för veckan |
+
+### Fitness-specifika Push-strategier
+

+# Progressive Overload-algoritmer — Research för Gravl
+
+## Vad är Progressive Overload?
+
+> "Progressive overload is the gradual increase of stress placed on the body during training. To continue building strength and muscle, you must progressively increase the demands on your musculoskeletal system."
+
+**Grundprincipen:** Om du gör samma träning med samma vikter, reps och sets vecka efter vecka har kroppen ingen anledning att anpassa sig.
+
+---
+
+## Progressionsmetoder
+
+### 1. Vikt-progression (Linear)
+
+**Enklast och mest effektiv för nybörjare/intermediates**
+
+```
+Vecka 1: Bänkpress 60kg x 8,8,8
+Vecka 2: Bänkpress 62.5kg x 8,8,8
+Vecka 3: Bänkpress 65kg x 8,8,8
+...
+```
+
+**Typiska ökningar:**
+| Övning | Ökning per pass |
+|--------|-----------------|
+| Squat/Deadlift | +2.5-5 kg |
+| Bench/Row/OHP | +1.25-2.5 kg |
+| Isolation (curls, etc.) | +1-2 kg |
+
+### 2. Rep-progression (Double Progression)
+
+**När du inte kan öka vikt varje vecka**
+
+```
+Mål: 3x8-12 reps
+
+Vecka 1: 60kg x 8,8,8 (låg end)
+Vecka 2: 60kg x 9,9,8
+Vecka 3: 60kg x 10,10,10
+Vecka 4: 60kg x 12,11,11
+Vecka 5: 62.5kg x 8,8,8 (öka vikt, börja om)
+```
+
+**Regel:** Öka vikt när alla sets når övre rep-gränsen.
+
+### 3. Set-progression
+
+```
+Vecka 1: 60kg x 8,8,8 (3 sets)
+Vecka 2: 60kg x 8,8,8,8 (4 sets)
+Vecka 3: 62.5kg x 8,8,8 (tillbaka till 3 sets, ny vikt)
+```
+
+### 4. RPE/RIR-baserad Autoregulation
+
+**RPE = Rate of Perceived Exertion (1-10)**
+**RIR = Reps in Reserve**
+
+| RPE | RIR | Beskrivning |
+|-----|-----|-------------|
+| 10 | 0 | Failure (kunde inte gjort fler) |
+| 9.5 | 0.5 | Kanske 1 till med dålig form |
+| 9 | 1 | 1 rep kvar |
+| 8.5 | 1.5 | 1-2 reps kvar |
+| 8 | 2 | 2 reps kvar |
+| 7 | 3 | 3 reps kvar |
+| 6 | 4 | Uppvärmning |
+
+**Konvertering:** `RPE = 10 - RIR`
+
+**Användning:**
+```
+Målsättning: 3x8 @ RPE 8
+
+Set 1: 80kg x 8 @ RPE 7 → för lätt, öka
+Set 2: 82.5kg x 8 @ RPE 8 → perfekt
+Set 3: 82.5kg x 8 @ RPE 9 → trötthet, behåll vikt
+```
+
+---
+
+## 1RM-beräkning
+
+### Populära formler
+
+#### Epley Formula (mest använd)
+
+```
+1RM = weight × (1 + reps/30)
+```
+
+**Exempel:** 80kg × 10 reps
+```
+1RM = 80 × (1 + 10/30) = 80 × 1.333 = 106.7 kg
+```
+
+#### Brzycki Formula
+
+```
+1RM = weight × (36 / (37 - reps))
+```
+
+**Exempel:** 80kg × 10 reps
+```
+1RM = 80 × (36 / (37 - 10)) = 80 × 1.333 = 106.7 kg
+```
+
+#### Lander Formula
+
+```
+1RM = weight × (100 / (101.3 - 2.67 × reps))
+```
+
+### Rep Max Tabell (% av 1RM)
+
+| Reps | % av 1RM | Vikt (om 1RM = 100kg) |
+|------|----------|----------------------|
+| 1 | 100% | 100 kg |
+| 2 | 94% | 94 kg |
+| 3 | 91% | 91 kg |
+| 4 | 88% | 88 kg |
+| 5 | 86% | 86 kg |
+| 6 | 83% | 83 kg |
+| 7 | 81% | 81 kg |
+| 8 | 79% | 79 kg |
+| 9 | 77% | 77 kg |
+| 10 | 75% | 75 kg |
+| 12 | 70% | 70 kg |
+| 15 | 65% | 65 kg |

+# Offline-First Implementation — Research för Gravl
+
+## Varför Offline-First?
+
+> "Mobile networks are unreliable. Users face data limits, weak signals, airplane mode, subway tunnels."
+
+**Gym-specifikt:**
+- Gym har ofta dålig/ingen WiFi
+- Källare, betong, metall = dålig signal
+- Användare vill inte vänta på laddning mellan sets
+- Data får INTE förloras (loggade reps är värdefulla)
+
+---
+
+## Offline-First Principer
+
+### Core Principles (från OneUptime)
+
+1. **Local-first:** Data sparas lokalt FÖRST, synkas SEN
+2. **Optimistic Updates:** UI uppdateras direkt, backend i bakgrund
+3. **Graceful Degradation:** Features som kräver nätverk degraderas snyggt
+4. **Conflict Resolution:** Tydlig strategi för datakonflikt
+5. **Transparent Sync:** Användaren förstår sync-status
+
+### Mental Model

+
+## Tekniska Alternativ
+
+### 1. React Native + SQLite
+
+**Bibliotek:** `react-native-sqlite-storage` eller `expo-sqlite`
+
+**Fördelar:**
+- Native performance
+- Full SQL-support
+- Beprövad teknologi
+
+**Nackdelar:**
+- Kräver native build
+- Ingen inbyggd sync
+
+```javascript
+import * as SQLite from 'expo-sqlite';
+
+const db = SQLite.openDatabase('gravl.db');
+
+// Skapa tabell
+db.transaction(tx => {
+  tx.executeSql(
+    `CREATE TABLE IF NOT EXISTS workout_logs (
+      id INTEGER PRIMARY KEY AUTOINCREMENT,
+      exercise_id INTEGER,
+      weight REAL,
+      reps TEXT,
+      synced INTEGER DEFAULT 0,
+      local_id TEXT,
+      created_at TEXT DEFAULT CURRENT_TIMESTAMP
+    )`
+  );
+});
+
+// Logga set (offline-first)
+const logSet = async (exerciseId, weight, reps) => {
+  const localId = uuid.v4();
+  
+  // Spara lokalt FÖRST
+  db.transaction(tx => {
+    tx.executeSql(
+      'INSERT INTO workout_logs (exercise_id, weight, reps, local_id) VALUES (?, ?, ?, ?)',
+      [exerciseId, weight, JSON.stringify(reps), localId]
+    );
+  });
+  
+  // Försök synka i bakgrund
+  syncToServer(localId);
+};
+```
+
+### 2. React Native + RxDB
+
+**RxDB:** Reactive Database med inbyggd sync
+
+**Fördelar:**
+- Reaktiv (observables)
+- Inbyggd sync (CouchDB-protokoll)
+- Conflict resolution
+- TypeScript-stöd
+
+**Nackdelar:**
+- Mer komplex setup
+- Större bundle
+
+```javascript
+import { createRxDatabase, addRxPlugin } from 'rxdb';
+import { getRxStorageDexie } from 'rxdb/plugins/storage-dexie';
+import { RxDBReplicationCouchDBPlugin } from 'rxdb/plugins/replication-couchdb';
+
+addRxPlugin(RxDBReplicationCouchDBPlugin);
+
+const db = await createRxDatabase({
+  name: 'gravldb',
+  storage: getRxStorageDexie()
+});
+
+// Schema
+await db.addCollections({
+  workouts: {
+    schema: {
+      version: 0,
+      primaryKey: 'id',
+      properties: {
+        id: { type: 'string' },
+        exercise_id: { type: 'number' },
+        weight: { type: 'number' },
+        reps: { type: 'array' },
+        timestamp: { type: 'string' }
+      }
+    }
+  }
+});
+
+// Replication
+const replicationState = db.workouts.syncCouchDB({
+  remote: 'https://api.gravl.app/sync',
+  push: { batchSize: 10 },
+  pull: { batchSize: 10 }
+});
+```
+
+### 3. PWA + IndexedDB + Service Worker
+
+**För web-first approach**
+
+**Fördelar:**
+- Ingen app store
+- Fungerar på alla plattformar
+- Service Worker caching
+
+**Nackdelar:**
+- Begränsad native-access
+- iOS PWA-begränsningar
+
+```javascript
+// Service Worker (sw.js)
+const CACHE_NAME = 'gravl-v1';
+const OFFLINE_URLS = [
+  '/',
+  '/app.js',
+  '/styles.css',
+  '/exercises.json'
+];
+
+self.addEventListener('install', event => {
+  event.waitUntil(
+    caches.open(CACHE_NAME).then(cache => {
+      return cache.addAll(OFFLINE_URLS);
+    })
+  );
+});
+
+self.addEventListener('fetch', event => {
+  event.respondWith(
+    caches.match(event.request).then(cached => {
+      // Returnera cached först, hämta nytt i bakgrund
+      const networkFetch = fetch(event.request).then(response => {
+        caches.open(CACHE_NAME).then(cache => {
+          cache.put(event.request, response.clone());
+        });
+        return response;
+      });
+      
+      return cached || networkFetch;
+    })
+  );
+});
+```
+
+```javascript
+// IndexedDB wrapper (Dexie)
+import Dexie from 'dexie';
+
+const db = new Dexie('GravlDB');
+
+db.version(1).stores({
+  workouts: '++id, date, synced',
+  exercises: 'id, name, bodyPart',
+  pendingSync: '++id, type, data, timestamp'
+});
+
+// Offline-first save
+async function saveWorkout(workout) {
+  // Spara lokalt
+  const id = await db.workouts.add({
+    ...workout,
+    synced: false,
+    localId: crypto.randomUUID()
+  });
+  
+  // Queue för sync
+  await db.pendingSync.add({
+    type: 'workout',
+    data: workout,
+    timestamp: Date.now()
+  });
+  
+  // Trigger background sync
+  if ('serviceWorker' in navigator && 'sync' in registration) {
+    registration.sync.register('sync-workouts');
+  }
+  
+  return id;
+}
+```
+
+### 4. SQLite Sync (CRDT)
+
+**Nytt:** SQLite Cloud's SQLite Sync extension
+
+**Fördelar:**
+- Äkta local-first
+- CRDT för konfliktfri sync
+- Standard SQLite API
+
+```javascript
+// SQLite Sync (konceptuell)
+import { SQLiteSync } from 'sqlite-sync';
+
+const db = new SQLiteSync('gravl.db', {
+  remote: 'https://sync.gravl.app',
+  tables: ['workouts', 'exercises']
+});
+
+// Automatisk sync!
+await db.exec(`
+  INSERT INTO workouts (exercise_id, weight, reps)
+  VALUES (1, 80, '[8, 8, 8]')
+`);
+// Synkas automatiskt när online
+```
+
+---
+
+## Sync Strategies
+
+### 1. Optimistic UI
+
+```javascript
+// Användaren ser ändringen DIREKT
+const logSet = async (data) => {
+  // 1. Uppdatera UI omedelbart
+  setWorkoutLogs(prev => [...prev, data]);
+  
+  // 2. Spara lokalt
+  await localDB.save(data);
+  
+  // 3. Synka i bakgrund (utan att blockera UI)
+  syncInBackground(data).catch(err => {
+    // Visa synkfel-indikator, men behåll data
+    showSyncError();
+  });
+};
+```
+
+### 2. Conflict Resolution
+
+**Strategier:**
+
+| Strategi | Beskrivning | Bäst för |
+|----------|-------------|----------|
+| **Last Write Wins** | Senaste timestamp vinner | Enkel data |
+| **Client Wins** | Lokal data prioriteras | User-kontroll |
+| **Server Wins** | Server-data prioriteras | Data integrity |
+| **Merge** | Kombinera ändringar | Komplex data |
+| **CRDT** | Konfliktfri automatisk | Multi-device |
+
+**Gravl-rekommendation:** Last Write Wins med server-timestamp
+
+```javascript
+const resolveConflict = (local, remote) => {
+  // Om samma workout redigerats på två enheter
+  if (local.updated_at > remote.updated_at) {
+    return local;  // Nyare vinner
+  } else {
+    return remote;
+  }
+};
+```
+
+### 3. Background Sync
+
+```javascript
+// Service Worker background sync
+self.addEventListener('sync', event => {
+  if (event.tag === 'sync-workouts') {
+    event.waitUntil(syncPendingWorkouts());
+  }
+});
+
+async function syncPendingWorkouts() {
+  const pending = await db.pendingSync
+    .where('type')
+    .equals('workout')
+    .toArray();
+  
+  for (const item of pending) {
+    try {
+      await fetch('/api/workouts', {
+        method: 'POST',
+        body: JSON.stringify(item.data)
+      });
+      
+      // Ta bort från queue
+      await db.pendingSync.delete(item.id);
+      
+      // Markera som synkad
+      await db.workouts
+        .where('localId')
+        .equals(item.data.localId)
+        .modify({ synced: true });
+        
+    } catch (err) {
+      // Retry later
+      console.log('Sync failed, will retry');
+    }
+  }
+}
+```
+
+---
+
+## Sync Status UI
+
+### Indikera sync-status
+
+```jsx
+// Sync-indikator komponent
+const SyncStatus = () => {
+  const { pendingCount, lastSync, isOnline } = useSyncStatus();
+  
+  if (!isOnline) {
+    return (
+      <StatusBar color="orange">
+        📴 Offline — Data sparas lokalt
+      </StatusBar>
+    );
+  }
+  
+  if (pendingCount > 0) {
+    return (
+      <StatusBar color="yellow">
+        ⏳ Synkar {pendingCount} ändringar...
+      </StatusBar>
+    );
+  }
+  
+  return (
+    <StatusBar color="green">
+      ✅ Synkad {formatTime(lastSync)}
+    </StatusBar>
+  );
+};
+```
+
+### Per-item sync status
+
+```jsx
+const WorkoutLogItem = ({ log }) => {
+  return (
+    <View>
+      <Text>{log.exercise} — {log.weight}kg × {log.reps}</Text>
+      {!log.synced && (
+        <Badge color="orange">Ej synkad</Badge>
+      )}
+    </View>
+  );
+};
+```
+
+---
+
+## Gravl Implementation Plan
+
+### Phase 1: Local Storage
+
+```
+1. Implementera SQLite/IndexedDB
+2. Spara ALL data lokalt först
+3. UI visar alltid lokal data
+4. Ingen sync ännu (100% offline)
+```
+
+### Phase 2: Basic Sync
+
+```
+1. Lägg till sync queue
+2. POST nya workouts till server
+3. Markera som synkade
+4. Retry on failure
+```
+
+### Phase 3: Bi-directional Sync
+
+```
+1. Pull server-ändringar
+2. Merge med lokal data
+3. Conflict resolution
+4. Multi-device support
+```
+
+### Phase 4: Real-time (optional)
+
+```
+1. WebSocket för live updates
+2. Optimistic UI
+3. Collaborative features
+```
+
+---
+
+## Database Schema (Offline-optimerad)
+
+```sql
+-- Local SQLite schema
+
+CREATE TABLE workouts (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    local_id TEXT UNIQUE NOT NULL,     -- UUID, genereras lokalt
+    server_id INTEGER,                  -- NULL tills synkad

+    program_day_id INTEGER,
+    started_at TEXT,
+    completed_at TEXT,
+    notes TEXT,
+

+    synced INTEGER DEFAULT 0,
+    sync_action TEXT DEFAULT 'create', -- 'create', 'update', 'delete'
+    local_updated_at TEXT,
+    server_updated_at TEXT,
+    
+    created_at TEXT DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE TABLE workout_sets (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    local_id TEXT UNIQUE NOT NULL,
+    server_id INTEGER,
+    
+    workout_local_id TEXT REFERENCES workouts(local_id),
+    exercise_id INTEGER,
+    set_number INTEGER,
+    weight REAL,
+    reps INTEGER,
+    rpe REAL,
+    
+    synced INTEGER DEFAULT 0,
+    created_at TEXT DEFAULT CURRENT_TIMESTAMP
+);
+
+CREATE TABLE sync_queue (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    table_name TEXT,
+    local_id TEXT,
+    action TEXT,  -- 'create', 'update', 'delete'
+    payload TEXT, -- JSON
+    attempts INTEGER DEFAULT 0,
+    last_attempt TEXT,
+    created_at TEXT DEFAULT CURRENT_TIMESTAMP
+);
+
+-- Index för snabb sync-lookup
+CREATE INDEX idx_workouts_synced ON workouts(synced);
+CREATE INDEX idx_sync_queue_attempts ON sync_queue(attempts);
+```
+
+---
+
+## Rekommendation för Gravl
+
+### Tech Stack
+
+```
+Frontend: React (web) eller React Native (app)
+Local DB: Dexie (IndexedDB wrapper) för web
+          expo-sqlite för native
+Sync:     Custom sync engine med retry logic
+Backend:  Befintlig Express/PostgreSQL
+```
+
+### Varför inte RxDB/CouchDB?
+
+- Overhead för ett simpelt use case
+- Gravl har enkel data (workouts, sets)
+- Custom sync ger mer kontroll
+
+### Nyckelprinciper
+
+1. **Lokal data är sanning** — Servern är backup
+2. **Aldrig blockera UI** — Sync sker i bakgrund
+3. **Aldrig förlora data** — Queue allt
+4. **Tydlig status** — Användaren vet vad som händer

+# Monetisering — Research för Gravl
+
+## Marknadsöversikt
+
+**Fitness app-marknaden:**
+- 2025: ~$10 miljarder
+- 2028 prognos: $15.6 miljarder
+- Health & Fitness är top-kategorin för app revenue
+
+**RevenueCat State of Subscription Apps 2025:**
+- Health & Fitness: $0.63+ revenue per install efter 60 dagar
+- Dubbelt median ($0.31 för alla kategorier)
+- Låga årspriser = bättre retention (36%)
+
+---
+
+## Monetiseringsmodeller
+
+### 1. Freemium (Mest vanlig)
+
+**Så funkar det:**
+- Gratis grundfunktioner
+- Premium låser upp avancerade features
+- Konverteringsmål: 2-5% free → paid
+
+**Fördelar:**
+- Låg tröskel för nya användare
+- Stort användarbas
+- Word-of-mouth
+
+**Nackdelar:**
+- Låg konverteringsrate
+- Kostnad för gratis-användare
+- Feature-balans är svår
+
+**Fitness-exempel:**
+- Hevy: Gratis loggning, premium för avancerade grafer
+- Strong: 3 gratis routines, premium för obegränsat
+
+### 2. Subscription (Prenumeration)
+
+**Så funkar det:**
+- Månads- eller årsbetalning
+- Ofta med free trial
+
+**Typiska priser (fitness):**
+| App | Månads | Års | Trial |
+|-----|--------|-----|-------|
+| FITBOD | $12.99 | $79.99 | 3 workouts |
+| Strong | $4.99 | $29.99 | 3 routines |
+| Hevy | $2.99 | $23.99 | Generous free |
+| Juggernaut AI | $35 | — | — |
+
+**Trial konvertering (benchmark):**
+- 25-60% trial → paid (bra apps)
+- 7 dagar vs 30 dagar: Ingen signifikant skillnad
+- "Pay upfront after trial" ökar konvertering
+
+### 3. Paymium
+
+**Så funkar det:**
+- Betala för att ladda ner + in-app purchases
+
+**2025 Insight:**
+> "Paymium has emerged as the dominant monetization strategy for fitness apps targeting engaged, high-value audiences."
+
+**Fördelar:**
+- Filtrerar bort tire-kickers
+- Högre ARPU
+- Mer engagerade användare
+
+**Nackdelar:**
+- Mycket lägre downloads
+- Kräver stark varumärke
+- Svårare discovery
+
+### 4. One-time Purchase
+
+**Så funkar det:**
+- En engångsbetalning, appen är din
+
+**Reddit-sentiment:**
+> "I'd happily pay $20 once for a good app. $100/year feels like a scam for a workout logger."
+
+**Verklighet:**
+- Svårt att underhålla utan löpande intäkt
+- Fungerar för simpla appar
+- Premium-tier kan vara one-time
+
+### 5. Ads
+
+**Fitness-användare HATAR ads:**
+> "Ads in the middle of my workout? Instant uninstall."
+
+**Om du måste:**
+- Aldrig mitt i workout
+- Endast i free-tier
+- Banner, inte interstitial
+
+---
+
+## Pricing Psychology
+
+### Principer som fungerar
+
+#### 1. Anchoring (Förankring)
+
+Visa det dyraste alternativet först:
+```
+┌────────────────────────────────────────┐
+│ Premium Yearly        $79.99/år        │  ← Anchor
+│ (Spara 50%!)          = $6.67/mån      │
+├────────────────────────────────────────┤
+│ Premium Monthly       $12.99/mån       │
+├────────────────────────────────────────┤
+│ Free                  $0               │
+└────────────────────────────────────────┘
+```
+
+#### 2. Price Framing
+
+```
+❌ "$79.99 per år"
+✅ "Mindre än en kaffe per vecka"
+✅ "Billigare än ett PT-pass"
+```
+
+#### 3. Decoy Effect
+
+Lägg till ett "dåligt" alternativ för att göra det önskade bättre:
+```
+Monthly: $12.99/mån
+Quarterly: $32.99/kvartal (= $11/mån) ← Decoy
+Yearly: $79.99/år (= $6.67/mån) ← Target
+```
+
+#### 4. Loss Aversion
+
+```
+"Du har tränat 47 pass i år. Uppgradera för att behålla din data!"
+"Din streak på 23 dagar — fortsätt med Premium!"
+```
+
+#### 5. Social Proof
+
+```
+"Gå med 50,000+ användare som blivit starkare med Gravl"
+"4.8 ★ på App Store"
+```
+
+---
+
+## Free Trial Best Practices
+
+### Trial Length
+
+**Research:**
+> "No significant difference between 7 and 30 day trials in conversion rate."
+
+**Rekommendation:** 7 dagar är standard, 14 dagar för fitness (tid att se resultat)
+
+### Trial Experience
+
+1. **Full access** — Låt användare uppleva ALLT
+2. **Onboarding** — Guida till value snabbt
+3. **Reminders** — "3 dagar kvar av trial"
+4. **Soft paywall** — "Trial slut, vill du fortsätta?"
+
+### Conversion Tactics
+
+```
+Day 1:  Welcome, visa premium features
+Day 3:  "Har du testat [killer feature]?"
+Day 5:  "Du har gjort X pass! Se din progress (premium)"
+Day 6:  "Sista dagen imorgon — 20% rabatt!"
+Day 7:  Soft paywall, erbjud förlängning
+```

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Gravl is a fitness/workout tracking app (PPL - Push/Pull/Legs) with progression tracking. The UI is in Swedish. It uses a React frontend, Express backend, and PostgreSQL database, deployed via Docker with nginx and Traefik.
+
+## Commands
+
+### Frontend (`frontend/`)
+```bash
+npm run dev       # Vite dev server on port 5173
+npm run build     # Production build -> dist/
+npm run preview   # Preview production build
+```
+
+### Backend (`backend/`)
+```bash
+npm start         # node src/index.js
+npm run dev       # nodemon with auto-reload
+```
+
+### Docker
+```bash
+docker compose up -d --build   # Build and run all services
+```
+
+### Database
+```bash
+psql -h localhost -U postgres -d gravl -f db/init.sql   # Initialize schema + seed data
+```
+
+There are no test or lint configurations.
+
+## Architecture
+
+### Frontend (React 18 + Vite, no TypeScript)
+- **Entry:** `main.jsx` sets up React Router v6 with `AuthProvider` context
+- **Top-level routing** (`main.jsx`): `/login`, `/register`, `/onboarding` use route guards (`AuthRoute`, `ProtectedRoute`)
+- **In-app navigation** (`App.jsx`): Uses `useState` view switching (not URL routes) between `'dashboard'`, `'profile'`, `'progress'`, `'select-workout'`, `'workout'`
+- **State:** `AuthContext` is the only shared state (token in localStorage, user profile). No Redux or other state libraries. Component-level state via `useState`
+- **API calls:** Direct `fetch()` in components with `API_URL = '/api'` constant. No shared API service layer
+- **Styling:** Plain CSS with custom properties for theming. Two files: `index.css` (globals) and `App.css` (~1900 lines, organized by component sections). Dark theme with orange accent (`#ff6b35`). Mobile-first, max-width 600px
+- **Icons:** Custom SVG icon library in `components/Icons.jsx` (no emoji usage per design decision)
+- **Pages directory:** `src/pages/` holds full-page components (`Dashboard.jsx`, `WorkoutPage.jsx`, `LoginPage.jsx`, `RegisterPage.jsx`, `OnboardingWizard.jsx`, `ProfilePage.jsx`, `ProgressPage.jsx`, `WorkoutSelectPage.jsx`)
+- **Input components:** `components/StepperInput.jsx` (pure controlled — no internal useState), `WeightInput.jsx` (2.5kg steps, kg suffix), `RepsInput.jsx` (1-rep steps). Used in workout set rows.
+
+### Backend (Express, single-file)
+- **All routes in `src/index.js`** — no separation into route files or controllers
+- **Auth:** JWT with 30-day expiry, `bcryptjs` for passwords, `authMiddleware` for protected routes
+- **Database:** `pg` with parameterized queries (`$1, $2` placeholders)
+- **Currently hardcodes program ID=1** in many queries
+- **Env vars (all have defaults):** `JWT_SECRET`, `DB_HOST`, `DB_PORT`, `DB_USER`, `DB_PASSWORD`, `DB_NAME`
+
+### Database (PostgreSQL)
+- Schema in `db/init.sql`: `users`, `programs`, `program_days`, `exercises`, `program_exercises`, `workout_logs`
+- Seeded with one PPL program (Push A/B, Pull A/B, Legs A/B) and 18 exercises
+
+### Deployment
+- Frontend: multi-stage Docker build (node -> nginx), nginx proxies `/api` to `gravl-backend:3001`
+- Backend: node:20-alpine container on port 3001
+- External PostgreSQL on `homelab` Docker network
+- Traefik reverse proxy at `gravl.homelab.local`
+
+## Conventions
+
+- Swedish language for all UI text, some variable names and comments
+- Functional components only, hooks throughout
+- Workout-type CSS color variables: `--workout-push`, `--workout-pull`, `--workout-legs`
+- Progression logic: increase weight by 2.5kg when all sets hit max reps
+- StepperInput is a pure controlled component — no internal useState, all state in parent
+- 44px minimum touch targets on all interactive elements (stepper buttons, inputs)
+- Input font-size ≥ 16px everywhere (prevents iOS auto-zoom on focus)
+
+## agents/ Directory
+
+Contains AI agent persona definitions (SOUL.md files) for different roles (architect, backend-dev, frontend-dev, coach, nutritionist, reviewer). The `coach/` directory also has exercise data, program definitions (beginner/hypertrophy/strength), and foods data as JSON.

+# Gravl Coding Conventions
+
+## Utvecklingsmetodik
+
+### Red/Green TDD (OBLIGATORISKT)
+
+All ny kod måste följa TDD-cykeln:
+
+```
+🔴 RED → 🟢 GREEN → 🔄 REFACTOR
+```
+
+#### 1. 🔴 RED - Skriv test först
+```javascript
+// test/feature.test.js
+describe('Feature', () => {
+  it('should do expected behavior', async () => {
+    const result = await feature.doSomething();
+    expect(result).toBe(expected);
+  });
+});
+```
+
+**Kör testet - det MÅSTE faila!**
+```bash
+npm test -- --grep "Feature"
+# ❌ FAIL (detta är rätt!)
+```
+
+#### 2. 🟢 GREEN - Minimal implementation
+Skriv bara tillräckligt med kod för att testet passerar:
+```javascript
+// src/feature.js
+export function doSomething() {
+  return expected; // Minimal lösning
+}
+```
+
+**Kör testet igen:**
+```bash
+npm test -- --grep "Feature"
+# ✅ PASS
+```
+
+#### 3. 🔄 REFACTOR - Förbättra
+Nu kan du:
+- Refaktorera för clean code
+- Extrahera funktioner
+- Förbättra namngivning
+- Ta bort duplicering
+
+**Kör testerna kontinuerligt:**
+```bash
+npm test
+# ✅ Alla test måste fortfarande passa
+```
+
+---
+
+## Teststruktur
+
+```
+/workspace/gravl/
+├── src/
+│   └── components/
+├── server/
+│   └── routes/
+└── test/
+    ├── unit/           # Enhetstester
+    ├── integration/    # API-tester
+    └── e2e/            # End-to-end
+```
+
+## Namnkonventioner
+
+### Tester
+- `[feature].test.js` - Unit tests
+- `[feature].integration.test.js` - Integration tests
+- Describe-block: Noun (vad testas)
+- It-block: "should [verb] [expected outcome]"
+
+### Commits
+```
+test: add failing test for [feature]
+feat: implement [feature] to pass tests
+refactor: clean up [feature] implementation
+```
+
+---
+
+## Workflow för kodningsagenter
+
+1. **Få uppgift** från Gravl PM
+2. **Läs spec** i docs/current-task.md
+3. **Skriv failing test** - visa PM
+4. **Implementera** tills test passerar
+5. **Refaktorera** om nödvändigt
+6. **Commit** med rätt prefix
+7. **Rapportera** till PM
