 ## Open
 
+- BUG/UI: the CSS duration tokens were retuned to 250/500 ms but `lib/motion.ts` still
+  carries 200/300, so JS animations (panels, dock, tabs) run at a different speed to CSS
+  transitions. They are meant to mirror each other; pick the intended values and update
+  `motion.ts` in both repos.
 - BUG/API: `pytest tests/` deletes every user on teardown (`tests/conftest.py`), so running
   it against the development database logs you out of the running app. Point tests at their
   own database, or reseed with `init_db` afterwards.
