"""FastAPI sidecar for kjvstudy.org static site deployment.

Handles routes that can't be pre-rendered as static HTML:
  - /search and /api/search (dynamic query)
  - /api/* (JSON API endpoints)
  - /*/pdf (on-demand PDF generation)
  - /random-verse (server-side redirect fallback)
  - /verse-of-the-day (redirect to today's date)
  - /og/* (dynamic OG images)

Runs on port 8001, proxied by nginx.
Uses gunicorn with uvicorn workers for resilience.
