# Frontend service: a featherweight nginx image serving the static SPA (web/),
# decoupled from the heavy ML API image. UI changes redeploy in ~minutes (this
# builds in seconds) instead of rebuilding the multi-GB backend.
#
# The API URL is injected at build time (--build-arg API_BASE=https://…) and
# written into app/config.js, so the prod endpoint stays out of the repo. With
# no API_BASE the committed config.js (empty → same-origin) is used as-is.
