Replace Go HTML template rendering with a Bun + TSX build-time static
site generator. Go backend becomes API-only for auth.
Frontend:
- Custom JSX-to-HTML-string factory (zero dependencies)
- TSX components for Header, Footer, index page, login page
- Client-side login.ts handles tab switching and fetch()-based auth
- Bun bundler compiles client JS, build.ts renders pages to dist/
Backend:
- Auth handlers return JSON (POST /api/login, POST /api/register)
- Login page served as static HTML from dist/
- Static assets served from /assets/ (public)
- Auth middleware unchanged (cookie check, redirect to /login)
- Removed template parsing and renderPage
Dockerfile:
- 3-stage build: Bun frontend -> Go backend -> alpine runtime
- Frontend dist copied to /app/dist in final image
Removed: templates/, static/css/ (replaced by frontend/)
