/// Tier 4 visual fidelity, ringing screen: 9.1 (pulsing amber halo), 9.6
/// (art geometry), 9.8 (snooze eyebrow icon). Item 9.5 (hero time metrics)
/// is covered in `pantalla_alarma_sonando_scaffold_test.dart`, which already
/// owned the pre-existing `heroTime`-equality assertion that item revises.
///
/// 9.1 is the one with real hazard: the prototype's halo is a literal CSS
/// `animation: pw-pulse 2.4s ease-in-out infinite`. This screen's dismiss
/// guard (`pantalla_alarma_sonando_dismiss_guard_test.dart`, protected,
/// byte-identical to `main`) calls `pumpAndSettle()` after every mount and
/// every interaction — an actually-infinite `AnimationController.repeat()`
/// anywhere in this widget's subtree would hang every one of those calls
/// forever, with no way to fix it since that file cannot be touched. The
/// halo below is a BOUNDED pulse (one grow/settle cycle, no `.repeat()`) —
/// genuine animated motion, but one that always finishes.
