# Single-container image for hosted demos (Railway, Fly, Render, any Docker host).
#
# Builds the frontend, then runs Django under gunicorn with WhiteNoise serving both
# the collected static files and the built SPA, so no nginx is needed. Postgres is
# external (DATABASE_URL). Build from the repo root:
#
#   docker build -f deploy/railway.Dockerfile -t timeline-demo .
#
# Required env at runtime: DATABASE_URL, DJANGO_SECRET_KEY, DJANGO_ALLOWED_HOSTS,
# DJANGO_CSRF_TRUSTED_ORIGINS. Optional: SEED_DEMO=1, REQUIRE_ACCOUNT_APPROVAL=0,
# PORT (defaults to 8000), WEB_CONCURRENCY.
