/* ============================================================
   fonts-i18n.css - per-locale type overrides for the landing site.

   WHY THIS FILE EXISTS: theme.css resolves the four type tokens to
   Black Han Sans / Cinzel / Rajdhani / JetBrains Mono, and their script
   coverage is NOT uniform. Only JetBrains Mono carries Cyrillic, none
   carries Thai, and Black Han Sans is Latin-BASIC so Turkish loses
   g-breve, s-cedilla and dotted-capital-I from every display heading.
   A locale whose glyphs are missing renders tofu or silently falls back to
   whatever the OS picks, and NO string-level check can see either: the
   translation is correct, the artifact is complete, every coverage metric
   reads 100%, and the page looks broken.

   So each affected locale re-points the tokens at a family that actually
   covers its script. The stylesheet is injected by landing/i18n.js (which
   loads on every localized page) and baked statically into landing/<seg>/.
   Locales whose script the shipped stack already covers (id, and Turkish
   for everything except the display token) declare no extra font file in
   scripts/lib/landingLocales.js and are handled by the overrides here alone.

   Guard: scripts/verify-landing-l10n.js (every shipping locale has a rule
   here, and the families it names are the ones its fontHref loads).

   Nothing in the shipped stack has Thai, including the mono token, so all
   four are re-pointed. Thai glyphs carry stacked marks above and below the

   marks of one line collide with the vowels of the next. */

   Cinzel, Rajdhani and JetBrains Mono all ship latin-ext, so brand, chrome
   and mono are already correct. Black Han Sans does NOT, so the display
   token alone is re-pointed at Rajdhani rather than loading a new family.
   That is why tr declares no fontHref: the fix is a substitution, not a
   download. */

   no-op rather than by an omission that looks identical. */
