# ══════════════════════════════════════════════════════════════
# Dockerfile — Next.js frontend + FastAPI backend (single container)
#
# The container runs both:
#   - FastAPI (uvicorn) on :8000  — the API backend
#   - Next.js (node)    on :3000  — the frontend (proxies /api/* to :8000)
#
# start.sh launches both processes.
