/* ==========================================================================
   Ember — design system
   Concept: "date the person, reveal the photo."
   Palette (brand-fixed hex, both themes draw from these):
     char  #1B1512 — charred base
     coal  #241C18 — dark surface
     ember #E8622D — primary glow (hot coal orange)
     amber #F2A94F — secondary glow (halo gold)
     wine  #6E2E3F — reveal/match accent (deep ember-wine, not swipe-app pink)
     ash   #9C8B82 — warm neutral
     paper #F6F1E9 — warm light surface
   Type: Fraunces (display, variable) + Karla (body, variable) — both self-hosted.
