/* ============================================================================
   STRONG INSURANCE — DESIGN SYSTEM TOKENS  (v4 · WARMED EDITION)
   Technique 4: Design-System / Component-Driven — small-town warm rebuild.
   Three-layer architecture preserved: PRIMITIVE -> SEMANTIC -> COMPONENT.

   What changed vs. the cold original (acting on the review: "a touch
   corporate/templated; coldest of the four"):
     • A WARM accent family (clay/terracotta + honey) now lives alongside Erie
       blue — warmth is a first-class part of the system, not a sparingly-used
       afterthought.
     • Surfaces moved from cool slate-50 to a soft warm LINEN/CREAM.
     • Shadows are warm-tinted (sienna), not cool navy — they feel like
       afternoon light, not a corporate boardroom.
     • Display type is a warm serif; body stays clean sans for trust + legibility.
     • Softer, rounder radii. A faint paper grain. Hand-feel, kept systematic.
   Erie blue #005fac is still the action/primary + the Erie co-brand badge.
