   - [x] `inline` flag plumbed (parser + list/detail endpoints); 3 quick tasks flagged.
   - [ ] 3c FileBrowser task action: `task.inline ? openModal : navigate('/jobs/new?...')`. Modal stays
         for inline tasks (not retired); shared input form used by both.
-  - [ ] 3d header running-jobs indicator (`GET /jobs?live=1`).
+  - [ ] 3d header job indicators — two always-present badges next to the avatar + reload-tasks:
+        (1) **running** count (0/1) → links to the running job's `/jobs/:id`;
+        (2) **queued** count → links to the queue (`/jobs`). Backed by a lightweight
+        `GET /jobs/counts` → `{ running, runningJobId, queued }`, polled while mounted (cheap, avoids
+        fetching full lists). Badges hide/dim at 0.
