name: release

# Release pipeline on a vX.Y.Z tag, in order:
#   1) build  — the SAME wasm-build.yml recipe as CI, but at -O2 (the shipped demo
#               opt level) + run the e2e gate; reuses main's opt-independent base
#               cache so only the asyncify/-O2 tail rebuilds. Uploads output/.
#   2) publish-wasm — push the -O2 build to the CDN (content-addressed, idempotent)
#               and write manifest-<tag>.json. The registry now reflects THIS tag.
#   3) deploy-demo  — build the standalone pinned to that manifest + deploy to
#               demo.pcbjam.com. So the demo can never point at stale wasm.
#
# Libraries are NOT published here (they change only on a KiCad lib-version bump):
# run publish-libs.yml once per LIB_TAG; this deploy just points the demo at
# libs/kicad/$LIB_TAG. WASM publishing is folded in here (no separate manual
# workflow), so the build that ships is exactly the build that was tested.
