+### Known minors (deferred from the toolbar review)

+- A Wayland error during the countdown counts as a tick: the timer is skipped instead of failing.
+- Each hover change allocates a full-output buffer; the pool can grow large on 4K.
+- Hover isn't set when the pointer enters and isn't cleared when it leaves.
+- On two monitors, a click on the other one doesn't close the bar (Esc does).
+- With the menu open, a click elsewhere closes the whole bar, and option changes made before a cancel aren't saved.
+- The toolbar doesn't take the capture lock: two bars can stack, and a capture started during the countdown makes the toolbar's capture fail.
+- The bar can cover a bottom panel, while the countdown pill sits above it.
