+# Issue #1437 – post the client bundle-size delta on every PR.
+#
+# Builds the app, compares total client JS against the committed baseline
+# (scripts/bundle-size-baseline.json), and publishes the delta table to the
+# job summary (visible from the PR checks tab — works for fork PRs, where
+# GITHUB_TOKEN is read-only and a comment API call would be rejected). For
+# same-repo branches it additionally upserts a sticky PR comment.
+#
+# The build runs with CI_SKIP_TYPECHECK=1: bundle size is orthogonal to the
+# repo's known type-error backlog, and measurement must not be hostage to it.
+# Actions pinned by SHA; version noted beside each.
