# Builds the docs and deploys a per-pull-request preview to Aleph Cloud using

# Cleanup: on every pull_request event the action first sweeps this repo's
# preview sites and removes the ones whose PR is now closed, then deploys the
# current PR's preview. Closed-PR previews are therefore reaped on subsequent
# PR activity - that is why we do NOT listen for the `closed` event (doing so
# would make the action reap then immediately redeploy the just-closed preview).
# Cleanup: we listen for the `closed` event so a PR's preview is torn down the
# moment it is closed or merged. On a `closed` event the action runs in
# cleanup-only mode (removes the preview, skips the deploy/comment steps); on
# the other event types it deploys/updates the preview as usual. Keep the full
# `types` list - dropping the defaults would stop previews deploying on push.
#
# One-time setup required (delegated signing - the CI key signs, the owner
# wallet pays and owns the sites):
