/*
 * Self-hosted fonts. NEVER load fonts from Google's CDN: serving them from

 * (3 O 17493/20, Jan 2022) held to breach GDPR without consent.
 *
 * Files: public/fonts/, from Fontsource (OFL-1.1; licences alongside).
 * Each face is split into latin and latin-ext subsets by unicode-range, so a
 * Portuguese page downloads only the latin file (ã õ ç á ê í º ª € are all in
 * latin). latin-ext downloads only if such characters actually render.
 *
 * Source Serif 4 ships at 600 only: 700 was dropped to hold the 120 kB font
 * budget (DESIGN.md "Typography").
 *
 * There are NO font preloads. Instead, text paints at once in a local system
 * font whose metrics are overridden to occupy almost exactly the same space
 * (see METRIC-MATCHED FALLBACKS below), so the swap to the real font when it
 * arrives does not shift the layout.
