   - Complexity: medium — new `tags: List[str]` field on all card entities; tag CRUD API; filter bar UI per section; tag badge rendering on cards; persistence migration
   - Impact: medium-high — essential for setups with many devices/targets; enables quick filtering (e.g. "bedroom", "desk", "gaming")
 - [x] `P3` **PWA / mobile layout** — Mobile-first layout + "Add to Home Screen" manifest
+- [ ] `P1` **Collapse dashboard running target stats** — Show only FPS chart by default; uptime, errors, and pipeline timings in an expandable section collapsed by default
+- [ ] `P1` **Review protocol badge on LED target cards** — Review and improve the protocol badge display on LED target cards
