# BloxOS dashboard image: Next.js standalone server, served same-origin
# with the hub behind one reverse proxy, so NEXT_PUBLIC_HUB_URL is empty.
#
# The build stage runs on the build platform: the output is JavaScript and
# static assets, and the dashboard never uses next/image (see next.config.ts),
# so no target-specific native module is needed. The runtime stage has no
# RUN steps, so a multi-platform build needs no emulation.
