 name: Release Please
 
+# Parked: manual-trigger only until the first 0.1.0 beta baseline.
+#
+# With no prior release and a 0.0.0 manifest, release-please tries to build one
+# initial release PR from all of main's history; that changelog overflows
+# GitHub's PR-body limit and the run fails on every push. Rather than baseline
+# on this (personal) repo only to redo it after the business-org migration, the
+# push trigger is disabled. Re-enable it (restore `on: push: branches: [main]`)
+# at beta time, once .release-please-manifest.json is seeded to 0.1.0 and a
+# curated v0.1.0 release/tag exists, so release-please manages 0.1.x onward
+# incrementally. Until then it can still be exercised by hand via the Actions
+# tab (workflow_dispatch).
