   Demo 03 — UI/UX Designer  ·  demos/03-ui-ux-designer/css/theme.css

   Design rationale
   ----------------
   Creative and typographic. Violet primary with a teal counterpoint on a
   near-white canvas, oversized display type and a lot of breathing room.
   Layout archetype E: an asymmetric bento grid that mixes text tiles, colour
   swatches and imagery, plus a horizontal process rail.

   ISOLATION CONTRACT
   Scoped to :root (token values) or .rp-demo--ui-ux-designer only.
