# Production image for ht_booking (Tenis Rajec).
#
# Three stages:
#   css     — compiles the Tailwind/daisyUI stylesheet with Node
#   builder — compiles the release binary with Rust
#   runtime — slim Debian image holding just the binary + assets
#
# Built and run via docker-compose.prod.yml — see DEPLOY.md.
