   Anton ships without Vietnamese diacritics, so when the active language is
   Vietnamese (i18n.php adds the .locale-vi body class) we reorder the display
   stack to prefer Be Vietnam Pro. Redefining the --font-display token on the
   scope means every element that already uses var(--font-display) — headings,
   .display, price figures, schedule headers, rating badge, avatars — switches
   automatically with no per-element overrides. Anton stays as the fallback so
   non-VI text is unaffected. A 700 weight keeps the heading impact since Be
   Vietnam Pro at 400 reads lighter than Anton. */
