+summary: Quick Add action buttons are no longer shrunk in shadcn themes.
+category: fix
+dev: Pins the .quick-entry-actions control height to literal :root tokens (28px desktop / 36px mobile) so shadcn's tighter --space-xl/--space-2xl scale no longer shrinks the composer (desktop + mobile).

 FN-7677 — the workflow trigger shares `.btn.btn-sm.dep-trigger` classes with other surfaces (InlineCreateCard, NewTaskModal, TaskDetailModal, TaskForm), but the shared `.dep-trigger, .inline-create-model-trigger` rule in styles.css sets `padding: 3px 8px`, overriding `.btn-sm`'s `padding: 4px 10px` and making this trigger ~2px shorter than its Save/Fast/Subtask `.btn.btn-sm` siblings in `.quick-entry-actions`. Re-assert `.btn-sm`'s own padding value scoped to this selector only (do not touch the shared global `.dep-trigger` rule — other surfaces still depend on its 3px/8px sizing) so the quick-add action row reads as one uniform height.
