+  Branch `refs/heads/design-dev/svos-retheme` is fetched into this repo as an
+  **inert ref** — nothing checked out, `main` clean, merge-tree clean.

   is **RELEASED** — design-dev does not touch it, so bug-hunt findings there
   land immediately. **HELD** while his branch is out: `base.html`, `view.html`,
