-Do **not** tip menu triggers (kebabs / ⋯ / `ActionsMenu` /
-`DropdownMenuTrigger`). The affordance is "open menu"; the verbs live in the
-menu. Never `"Actions for ${row title}"`, `"Project actions"`, `"Actions"`, or

-control whose visible label already says what the tip would.

 with the themed `Tip`. `src/components/ui/__tests__/no-native-title.test.ts`
