# Render the runtime API base into /env.js before nginx starts.
# The official nginx image runs every executable /docker-entrypoint.d/*.sh at
# startup, so this fires on each container boot — letting one image serve staging
# (API_BASE=https://fleetapi.fivetitude.com) and prod (…rahamafresh.com) from the
# same build. Only ${API_BASE} is substituted; index.html falls back to the prod
# API if it's empty.
