# Hostname the local stack is served under. Never .env's DOMAIN: a checkout
# configured for a deployment carries that deployment's domain, and a local
# stack started under it answers to the same names the live instance does.
# Target-specific on purpose — an exported DOMAIN outranks --env-file in
# compose interpolation, which would put the *production* targets on localhost.
# `make dev DOMAIN=fluksio.com` still wins.

# The frontend is an nginx image, so a UI change needs a rebuild. Both the
# domain and the overlay set come off the *running* stack rather than from a
# file: VITE_API_URL is baked in at build time, so rebuilding under a different
# domain — or without the lan overlay a stack was started with — leaves the SPA
# calling an API that answers elsewhere. The lan overlay is what publishes the
# host port and builds with an empty VITE_API_URL, so dropping it takes a wall
# panel reaching http://<host-ip>:$(APP_PORT) off the air entirely and bakes a
# name it cannot resolve into the bundle. A published host port is how that
# overlay is recognised, because it is the thing only that overlay adds.
