- ExerciseResearchPanel: add ProviderBadge component showing which AI
tier (Ollama/Gemini/OpenRouter/OpenCode/Exa) served the response
- Add auto-retry on 429/503 with 2s delay and retry counter in button
- Normalize error messages for common failure modes (network, rate-limit)
- ResearchDisplay: pass onRetry prop to error state for inline retry button
- CSS: .research-panel-controls flex row, .provider-badge with per-provider
colour coding, .rd-error-actions + .rd-retry button styles
- Add ResearchDisplay.jsx: pure presentational component for research
data with loading skeleton, accessible error state, and source cards
- Refactor ExerciseResearchPanel to delegate rendering to ResearchDisplay
(separates fetch/state logic from display)
- Add ExerciseEncyclopediaPage.css: full dark-theme stylesheet using
CSS variables (--bg-*, --text-*, --accent, --border, --radius-*)
replacing the light-theme WorkoutEditPage.css import
- Update ExerciseEncyclopediaPage.jsx: new semantic class names,
keyboard-accessible card toggle (Enter key + role=button + aria-expanded)
- Mobile-responsive at 600px breakpoint
