# Compose reads variable defaults from a `.env` file in this directory.
# Copy `.env.example` to `.env` and fill in your values, then `docker compose up -d`.
#
# Variables consumed at BUILD time (changes need `docker compose up --build`):
#   NEXT_PUBLIC_ROOM_WS_URL
#   NEXT_PUBLIC_PROVIDER_{ALPHA,BETA,GAMMA,DELTA}_{NAME,ORIGIN,MOVIE,TV}
#
# Variables consumed at RUNTIME (just `docker compose up -d`):
#   TMDB_API_KEY (required)
#   GIPHY_API_KEY (optional — enables the chat GIF picker)
#   ROOM_ALLOWED_ORIGINS
#   WEB_PORT, ROOM_PORT (host ports)
#
# Optional Caddy reverse proxy (TLS + single-origin routing for /ws):
#   docker compose --profile proxy up -d --build
#   Default is HTTP-only on :80 (good for local docker/ngrok). For production
#   with auto-HTTPS, set SITE_ADDRESS=yourdomain.com in .env.
