Replaced REST API dependency with @valknarthing/pastel-wasm (130KB) for
complete browser-based color operations. The application is now fully
static (2.2MB total) with zero network latency and offline support.
**Key Changes:**
1. **WASM Integration:**
- Added @valknarthing/pastel-wasm dependency (0.1.0)
- Created lib/api/wasm-client.ts wrapper matching API interface
- Updated lib/api/client.ts to use WASM client by default
- All 18 color operations now run locally in browser
2. **Static Export Configuration:**
- Changed next.config.ts output from 'standalone' to 'export'
- Disabled image optimization for static export
- Removed API proxy route (app/api/pastel/[...path]/route.ts)
- Updated package.json scripts (removed dev:api, added serve)
3. **Docker Optimization:**
- Migrated from Node.js standalone to nginx-alpine
- Created nginx.conf with SPA routing and WASM mime types
- Updated Dockerfile for static file serving
- Reduced image size from ~150MB to ~25MB
- Changed port from 3000 to 80 (standard HTTP)
- Simplified docker-compose.yml (removed pastel-api service)
4. **Documentation Updates:**
- Updated README.md with WASM benefits and deployment options
- Added Key Benefits section highlighting zero-latency features
- Rewrote deployment section for static hosting platforms
- Updated CLAUDE.md tech stack and architecture
- Removed obsolete docs: DEV_SETUP.md, DOCKER.md, IMPLEMENTATION_PLAN.md
**Benefits:**
- 🚀 Zero Latency - All operations run locally via WebAssembly
- 📱 Offline First - Works completely offline after initial load
- 🌐 No Backend - Fully static, deploy anywhere
- ⚡ Fast - Native-speed color operations in browser
- 📦 Small - 2.2MB total (130KB WASM, 2.07MB HTML/CSS/JS)
**Deployment:**
Can now be deployed to any static hosting platform:
- Vercel, Netlify, Cloudflare Pages (zero config)
- GitHub Pages, S3, CDN
- Self-hosted nginx/Apache
- Docker (optional, nginx-based)
