# Dockerfile — Next.js 16 web-ui (ui-rewrite branch only)
#
# This file REPLACES the FastAPI Dockerfile on this branch so that
# Coolify's default /Dockerfile lookup builds the new Next.js staging
# UI. The FastAPI Dockerfile lives on `main` and is unaffected.
#
# When the rewrite is merged to main, decide between:
#   (a) keeping both via separate Dockerfiles + dockerfile_location config, or
#   (b) a multi-stage Dockerfile that serves both, or
#   (c) fully replacing FastAPI's StaticFiles with this Next.js front end.
