/* BNC Classic · self-hosted fonts. Loaded from this origin, so no third party can hold up the first paint.
 *  - Archivo (variable: wght 100–900, wdth 62–125): headlines, big figures, the countdown. Google Fonts "latin" subset.
 *  - BNCS Display SC = Noto Sans SC 900 (OFL), only the characters a heavy heading can show: every zh string that feeds a
 *    display heading (h1, section h2 incl. 怎么玩 / 推广工具 / 常见问题 / 术语, step and card titles, glossary terms, § titles,
 *    FOMO and dialog titles, 燃烧凭单, the hero cards, poster text, tab labels) plus what a live probe of the page finds
 *    (234 characters, 35 KB). A locally installed Noto Sans SC Black is preferred when present.
 *    When a heading's text changes, regenerate: node artifacts/site-review/final/fonts/display-chars.mjs, then
 *    python artifacts/site-review/final/fonts/fetch_display_sc.py (keeps every character the old subset had).
 *  - IBM Plex Sans (variable) for UI and every figure (tabular), IBM Plex Mono for hashes and codes.
 *  - Noto Sans SC (body CJK) still comes from Google Fonts without blocking the first paint (index.html); the system CJK font
 *    (PingFang SC / Microsoft YaHei / Noto Sans CJK) is used until, or unless, it arrives.
 *  - The *Fallback faces are local fonts scaled toward the web fonts' metrics, so the swap barely moves the layout. */
