/* Aubade Patient App — CSS
   Brand restyle (2026-08-03 audit remediation, item 10): dawn palette per
   BRANDBOOK.md (Pre-dawn Indigo / Deep Night / First Light / Horizon Rose /
   Slate Mist / Bone / Ink / Ember / Meadow), Fraunces for display type,
   Inter for body — both self-hosted (see fonts.css), no external CDN.
   Dark circadian theme retained (ADHD-accessible: high contrast, no
   clutter) — the dawn gradient runs dark-to-light, so a dark app shell with
   warm gold/rose highlights is the on-brand execution, not a departure
   from it. */
