/* ==========================================================================
   Demo 02 — App Developer  ·  demos/02-app-developer/css/theme.css

   Design rationale
   ----------------
   Light, airy and app-like. Indigo primary with a pink accent, generous
   rounding and soft shadows — the visual language of a modern mobile OS
   rather than a website. Layout archetype D: a centred hero holding a real
   phone mockup, then alternating feature rows and a card-based body.

   ISOLATION CONTRACT
   Scoped to :root (token values) or .rp-demo--app-developer only.
