# Client Board — production image for Coolify.
#
# This container is the Next.js app ONLY. PocketBase is a separate, already-
# hosted service (see docs/superpowers memory: "Coolify-only PocketBase") —
# this Dockerfile does not run or bundle it.
#
# NEXT_PUBLIC_APP_URL and NEXT_PUBLIC_PB_URL are inlined into the client
# JavaScript bundle at BUILD time, not read at container start. Coolify must
# be told to pass them as build arguments (its "Build Variables" section),
# not just as runtime environment variables — a value only set at runtime
# will be missing from the browser bundle entirely.
