/* Fonts (ADR-020 §18): Noto Sans cut into one file per script, the weight axis kept to 400–700, each file at most 40 KB.
   A page preloads only its language's script (App.razor), and the browser fetches another only for the characters
   that need it. Made from the design system's variable files with fonttools: varLib.instancer wght=400:700 wdth=100,
   then subset to these unicode ranges (Google Fonts' latin, latin-ext, cyrillic and cyrillic-ext, with ₾ in latin).
   "Noto Sans Fallback" is the local Arial (or Roboto) sized to Noto Sans's metrics, so text doesn't shift when the
   font swaps in. */
