/*
 * ATLAS — Canonical shared stylesheet
 *
 * Introduced with the blog system (July 2026).
 * Existing pages (index.html, booking.html, etc.) still use inline CSS and will
 * migrate to this file in a follow-up PR. Do NOT modify the tokens here without
 * also updating those inline blocks.
 *
 * Contents:
 *   1. Design tokens (CSS custom properties)
 *   2. Reset
 *   3. Base typography
 *   4. Blog shell (nav, hero, footer)
 *   5. Blog article prose
 *   6. Blog CTA block
 *   7. Blog index listing
