Issue 3 (feedback-pruebas): t4:427 wraps the POSPONER eyebrow, the
snooze tiles and the Stop button in a single flex column with a
uniform gap:12 -- this screen carried a 10/14 pair instead, matching
neither the prototype nor each other.
The dismiss-guard test (protected, untouched) only asserts behaviour
via find.text/find.byType, so this pure value change is safe against
it -- re-verified empty diff after this commit.
