   LICITA DESIGN SYSTEM — Webdesign layouts Library (v2.1)
   Warm editorial: terracotta accent, serif display, warm paper surface.
   Editorial SaaS layout-first. Contrast hardened per WCAG AA audit:
   - ink-mid #3C4554 (8.7:1 on paper), muted #46535C (7.2:1 on paper)
   - signal-text #9A3A24 for all small signal text (kicker/plan/chips)
   - code-card accent #e8a37b on ink bands
   Public surfaces must keep stable: /styles.css, all pages, /llms.txt.
