Tier 4 visual fidelity, audit 9.1/9.5/9.6/9.8 (t4 lines 411-428):
- 9.1: new _HaloPulsante renders the prototype's 420px amber radial
gradient behind the hero content. Deliberately BOUNDED (one
grow-and-settle cycle), not the prototype's literal `infinite` CSS
animation: this screen's protected dismiss-guard test calls
pumpAndSettle() after every mount/interaction, and a genuinely
infinite AnimationController.repeat() would hang it forever with no
way to fix it. Skips its Animate wrapper under reduced motion, same
as every other entry animation in this app.
- 9.5: the hero time gets a local letterSpacing/height override
(-4/0.95) instead of the shared heroTime token's -2.0/1.0 — the
alarm editor's hour block is the token's other consumer and still
wants height:1, so the shared style is untouched.
- 9.6: ringing-screen art grows from 168/radiusLg(30) to 180/36 (t4
line 421), a local constant like the existing stop-button radius.
- 9.8: the POSPONER eyebrow regains its 19px warmCoral snooze icon.
All 5 protected files (including the dismiss-guard test) remain
empty-diff against main.
