/* Self-hosted web font (SIL OFL — redistribution permitted).
   Inter = primary sans-serif, used for both body and headings.
   6 discrete weights × 7 unicode subsets = 42 @font-face declarations.
   Subsets: cyrillic-ext, cyrillic, greek-ext, greek, vietnamese,
   latin-ext, latin. The browser fetches ONLY the subsets whose code
   points appear on the page (unicode-range mechanic), so the on-disk
   footprint (~1.2MB) does not translate to per-request bandwidth —
   English/Malay traffic only pulls the latin subset (~24KB per
   weight). Inter does NOT ship CJK / Arabic / Hebrew / Thai /
   Devanagari glyphs — those code points fall through the font stack
   to Noto / system fonts. */
