Critical fix for production deployment on Proxmox/Docker.
Problem:
- Runtime error: Prisma Client could not locate Query Engine for "debian-openssl-1.1.x"
- Wrong binary target generated (Windows dll instead of Linux .so.node)
- Wrong OpenSSL version (3.0.x instead of 1.1.x for Debian 11)
Root cause:
- Schema.prisma didn't specify binaryTargets
- Prisma auto-detected Windows during local development
- Debian 11 (bullseye) uses OpenSSL 1.1.x, not 3.0.x
Solution:
1. Add binaryTargets to schema.prisma:
- "debian-openssl-1.1.x" for Docker/Proxmox
- "native" for local development
2. Fix Prisma folder permissions in Docker:
- RUN chown -R nextjs:nodejs /app/prisma
- Ensures Query Engine binary is readable by app user
Changes:
- prisma/schema.prisma: Add binaryTargets = ["debian-openssl-1.1.x", "native"]
- keep-notes/Dockerfile: Add chown for /app/prisma folder
Verification:
✓ libquery_engine-debian-openssl-1.1.x.so.node exists
✓ Permissions: nextjs:nodejs (readable)
✓ Prisma Client loads successfully in container

## Bug Fixes
### Note Card Actions
- Fix broken size change functionality (missing state declaration)
- Implement React 19 useOptimistic for instant UI feedback
- Add startTransition for non-blocking updates
- Ensure smooth animations without page refresh
- All note actions now work: pin, archive, color, size, checklist
### Markdown LaTeX Rendering
- Add remark-math and rehype-katex plugins
- Support inline equations with dollar sign syntax
- Support block equations with double dollar sign syntax
- Import KaTeX CSS for proper styling
- Equations now render correctly instead of showing raw LaTeX
## Technical Details
- Replace undefined currentNote references with optimistic state
- Add optimistic updates before server actions for instant feedback
- Use router.refresh() in transitions for smart cache invalidation
- Install remark-math, rehype-katex, and katex packages
## Testing
- Build passes successfully with no TypeScript errors
- Dev server hot-reloads changes correctly
- Add debounced state updates for title and content (500ms delay)
- Immediate UI updates with delayed history saving
- Prevent one-letter-per-undo issue
- Add cleanup for debounce timers on unmount
