- Generate and add app/web/static/css/output.css
- Stop ignoring output.css in .gitignore
- Ensure UI has styles without requiring local Tailwind build step
Issues fixed:
1. Web Worker localStorage error - Remove localStorage calls from worker
- Worker cannot access localStorage (browser context only)
- Worker now sends data to main thread via postMessage
- Main thread handles all localStorage operations
2. Add favicon to avoid 404 error
- Use inline SVG favicon (llama emoji)
- No external file request
3. Optimize Tailwind CSS for production
- Add tailwind.config.js for content scanning
- Add app/web/static/css/input.css (Tailwind directives)
- Update package.json with tailwind build commands
- Update Dockerfile multi-stage build:
* Stage 1: Node.js - compile Tailwind CSS
* Stage 2: Python - install dependencies
* Stage 3: Runtime - use compiled CSS
- Update index.html to use compiled output.css
- Add fallback to CDN for development
4. Add DEVELOPMENT.md documentation
- Setup instructions for local development
- Tailwind CSS workflow (watch mode)
- Docker build explanation
- Development tips and best practices
Benefits:
- No more localStorage errors in console
- No more 404 favicon requests
- Optimized CSS for production (~30KB minified)
- Clear development workflow
- Multi-stage Docker build is efficient (~300MB image)
