/* ============================================================
   ASHEN THRONE - SITE THEME (single source of truth)
   Loaded FIRST on EVERY page (marketing + hub + mint).
   Owns: fonts, design tokens, the shared site header, the
   shared site footer, and the shared button/eyebrow/title
   primitives. Page stylesheets (style.css, seo.css, mint.css,
   hub.css) hold page-specific layout ONLY and must not
   redeclare tokens or chrome.

   Type system (matches the GAME's declared identity in
   client/styles.css - the site is where these webfonts
   actually load):
     --font-display  Black Han Sans   hero wordmark, section titles
     --font-chrome   Rajdhani         nav, buttons, labels, headers
     --font-mono     JetBrains Mono   data: hashes, prices, terminal
     --font-body     system sans      long-form paragraphs

   Guard: scripts/verify-hub-shell.js (theme-first load order,
   header parity, token ownership).

/* ── zh-Hant (Traditional Chinese) font fallbacks ──────────────────────────
   The Latin display faces (Black Han Sans / Cinzel / Rajdhani) carry no CJK
   glyphs; give every stack a Noto TC fallback so translated text renders in a
   matching weight instead of the system default. The Noto stylesheet is
   loaded only when the locale is active: landing/i18n.js injects it at
   runtime (hub pages) and scripts/l10n-landing-bake.js bakes the <link> into
   landing/zh/index.html (data-i18n-fonts="zh-Hant" both ways). */
