/* ==========================================================================
   StoryFawn — Lander pattern
   Reusable pattern for the gift-lander family (grandparent / last-minute /
   holiday / from-afar). Full-bleed scene hero + floating pill nav + eyebrow/
   headline + 46ch body + square gold CTA + square-cornered hairline cards.

   Tokens are consumed from sf-helen.css (--sf-*). This file defines NO new
   colors — it only lays out the pattern described in DESIGN-SPEC.md §§3-5.
