// The HACS submission check does not read hacs.json to find the integration: it
// globs `*manifest.json` over the whole clone of the DEFAULT branch and exits 1
// unless there is exactly one (hacs/default, scripts/helpers/integration_path.py
// -> "No manifest"). Two stand-only manifests under demo/stand turned the
// Hassfest job of PR #9004 red on 2026-08-11, five weeks into the review queue,
// and the failure said nothing about which file was to blame. Anything that
// needs a second manifest ships it as `manifest.template.json` and renames it at
// install time — see demo/stand/install.sh.
