🚀 Getting Started

cd /home/afterhours/OfflineU2
npm run dev          # Starts on http://localhost:5001

---

⚠️ Known Minor Issues (Non-Blocking)

1. COURSES_ROOT references in app/scan/page.tsx and app/settings/page.tsx - should use dynamic settings
2. lastWatched type mismatch - Prisma returns Date, API expects string (watch page parent)
3. TypeScript errors in WatchComponents.tsx, VideoPlayer.tsx, KeyboardShortcutsOverlay.tsx - cosmetic, don't affect runtime

---

📝 History Notes

• Renamed from OfflineU2 → OfflineAcademy (brand cleanup)
• WatchPageClient.tsx completely rewritten to fix TypeScript JSX parsing issues
• Progress API fixed to use valid Prisma unique key (@@unique([userId, lessonId]))
• Type declarations added for lucide-react and @radix-ui/react-separator

Generated for workspace transfer - all features functional as of last session.
