- Copy Flask v3.1 HTML templates (index.html, login.html) to backend/templates/ - Add Jinja2 support to FastAPI main.py - Update all JavaScript fetch() calls to use /api/* endpoints - Add JWT authentication to all requests (Authorization: Bearer token) - Implement automatic token refresh on 401 errors - Store JWT tokens in localStorage Benefits: - 100% identical UI to Flask v3.1 (proven, working design) - Gold gradient, Montserrat font, all animations preserved - FastAPI backend (Redis sessions, JWT auth, async) - No React rewrite needed - All features work immediately UI now matches Flask exactly while using modern FastAPI backend.
