# Run the prod-built app in a container, pulling env vars from .env.local
# (if present) or from the shell. No build-time secrets — every env value is
# read at container start by Next's standalone server.
#
# Usage:
#   docker compose up --build
#   APP_PORT=8080 docker compose up    (override host port)
#
# Compose v2.24+ (required for `env_file: path/required` syntax).
