Context

From ROADMAP.md (P1 - Security hardening).

api.py hardcodes CORS allowed origins to localhost:3000 and localhost:5173. When the frontend is served from a real domain this blocks all browser requests.

What to do

  1. Introduce a CORS_ALLOWED_ORIGINS environment variable (comma-separated list of origins).
  2. Update api.py to read this variable and pass the list to FastAPI's CORSMiddleware.
  3. Fall back to the current localhost values when the variable is unset (preserves dev behaviour).
  4. Add the variable to docker-compose.yml as a commented example and to DEPLOYMENT.md.

Acceptance criteria

  • Setting CORS_ALLOWED_ORIGINS=https://sparc.example.com allows requests from that origin.
  • Omitting the variable keeps the existing localhost defaults.
  • No hardcoded origin strings remain in api.py.
