# Core UI build
#
# Builds the React community app in ui/ and copies it onto web/dist, the
# //go:embed target. The community app builds to its own dist and stays
# unaware of the repo layout; this script does the placement.
#
# This produces the embed artifact only. The full UI gate (typecheck,
# tests, colour tokens, boundary check) runs as its own CI job, not here,
# so the server build stays fast.
#
# The previous Svelte UI is archived at the tag ui-svelte-final; restore it
# by checking that out.
