/* ════════════════════════════════════════════════════════════
   CYDUCK — A′ SANCTUARY (shared chassis)
   v1.0 — 5 May 2026

   This file provides the shared chassis for all A′ Sanctuary pages
   on cyduck.com (homepage, tools, manifesto, legal, contact, 404).

   Architecture:
   - This stylesheet is CACHED across pages (single ~6KB gzip download).
   - Each page additionally inlines page-specific CSS (3-5KB) for
     above-the-fold styles unique to that page.
   - Linked AFTER shared/common.js, BEFORE shared/sanctuary.js.

   Not used by:
   - Dashboard (uses dashboard/css/*)
   - Legacy TR pages (use shared/style.css until Phase 4 migration)
   - /game (independent retro design system)
