name: deploy-demo (manual re-deploy)

# MANUAL re-deploy of demo.pcbjam.com WITHOUT rebuilding/publishing WASM — it
# snapshots the WASM already in the registry into manifest-<tag>.json, publishes
# the gallery, builds the standalone, and deploys. Use it to re-ship the demo for
# an existing tag (e.g. a Pages config fix) when the WASM is already published.
#
# The tag-triggered release pipeline lives in release.yml (build -O2 → publish
# WASM → deploy), so a tag NO LONGER triggers this — this is the manual escape
# hatch only. If the registry has no WASM for the tag, the snapshot step fails
# (run release.yml, which builds + publishes). See docs/features/demo-deploy/.
