/* Warna diambil langsung dari tailwind-src.css (--color-primary/accent/ink/surface/line/ok/fix).
   Token tambahan (ink-dim/ink-faint/surface-2/line-soft/warn) adalah perluasan, bukan dari tailwind-src.css.
   Font Fraunces+IBM Plex adalah arah baru (bukan warisan tailwind-src.css yang aslinya system-font). */
