+#   2026-08-26 FIX: FOLDER_STACKS/FOLDERS detection (grep -E '^[^/.][^/]*/')
+#   matches ANY non-dot top-level folder in the changed-files list, including
+#   deploy/ — the shared tooling folder, not a stack. A PR touching only
+#   deploy/envparse.py caused stack-deploy.sh to be invoked with "deploy" as
+#   a stack name, which correctly errored ("No main compose file... in
+#   .../deploy") since deploy/ has no deploy.yaml. No live service was
+#   affected (the error occurs before any redeploy), but it produced a
+#   confusing pipeline failure on an otherwise-correct change. deploy/ is
+#   already unconditionally rsynced at the top of the deploy step regardless
+#   of which stacks changed, so it's safe to exclude it from the stack list
+#   everywhere folders are detected below.
