   Warm paper canvas · navy ink · gold as a DOCUMENT ACCENT (REF headers,
   stamps, ledger panels, ruler marks). Like a Hong Kong old-school law
   firm / bank / university-press document — not a recruitment brochure.
   Palette:  Warm paper #f7f4ef · Navy ink #0B1F3A · Gold #C8A24B.
   Fonts:    Fraunces (EN display serif) + Noto Serif TC (TC display)
            Inter + Noto Sans TC (body) · IBM Plex Mono (kickers / refs)
   Pairs with assets/js/lang.js — EN ⇄ 繁中, no reload, localStorage.
   ANTI-SLOP: no glow, no glassmorphism, no gradient text, no gradient
             fills/overlays, no emoji, no centred hero + 4 number cards,
             no uniform rounded card grid. Flat, matte, document-like.
