/* CruiseCrew website styles
 *
 * Design system inherited from Mathory (see spec §3–§6) with Heritage
 * palette substitution. Keep this file in sync with the Tailwind config
 * in admin_portal/tailwind.config.js (Phase 2 work) — palette values are
 * duplicated between the two projects.
 *
 * Font subset loaded from Google Fonts:
 *   family=Playfair+Display:ital,wght@0,400;0,500;0,600;0,700;1,400;1,600
 *   &family=Inter:wght@400;500;600;700
 *
 * Display face switched from Fraunces → Playfair Display on 2026-09-22 —
 * Fraunces's warm-humanist stroke modulation read as "italic-adjacent"
 * even in roman, which the intended editorial-but-readable positioning
 * did not want. Playfair Display is a classical transitional serif with
 * unambiguously roman upright shapes. Also matches the mobile app's
 * Heritage theme display face (see carcruise_mobile/lib/app/theme.dart).
 * Any residual `font-variation-settings: "opsz" X` calls were stripped
 * from this file at the same time — Playfair Display has no opsz axis,
 * so the properties silently no-op and become dead code.
 *
 * All tokens use \b word-boundary variable names to avoid collisions if
 * a future consumer scopes CSS.
