Changes: 1) Added refresh button to custom workout cards (visible only on 'Anpassad' workouts). 2) Implemented handleResetClick + handleConfirmReset flow with confirmation dialog ('Är du säker? Dina ändringar kommer att försvinna...'). 3) DELETE /api/custom-workouts/:id endpoint verified (exists in backend). 4) Added CSS styling: .reset-btn (orange icon button with hover effects), .success-message (green slide-down animation), .modal-overlay/.modal-dialog/.modal-btn (reusable confirmation dialog). 5) Added refresh icon to Icons.jsx SVG library. Frontend build successful with no errors.",

UI updates show badge change from 'Anpassad' to 'Program' after reset. Next: 04-06 (persistence improvements or advanced features like workout export/backup).",
