# J621-Frontend — builds the SPA and serves it as static files.
#
# Build context is the repository root, e.g.:
#   docker build -f deploy/J621-Frontend -t j621-frontend .
#
# This container only serves the SPA (with the index fallback). The public
# entry point is the separate "nginx" reverse-proxy service in the compose
# files, so API routing stays in one place.
