# Multi-stage: Vite production build runs during `docker build` / `docker compose build` —
# no `npm run build` on the host first. The final image is nginx + freshly built `dist/`.
#
# Unity still exports into Needle/<app>/assets/ on your machine; include that folder in the
# build context when it exists (it is not listed in .dockerignore). Clones without `assets/`
# need a Unity export (or committed assets) before the image can bundle a valid scene.
