/*
 * Self-hosted web fonts for the public pages. No requests to Google Fonts.
 *
 * Unbounded (headings, 500/700) and Golos Text (body, 400/500/600/700; 600 for
 * the lesson title in the app header, Fontsource 5.3.0), both under
 * the SIL Open Font License 1.1 (see ../fonts/*-OFL.txt). Files come from the
 * Fontsource packages, split by subset: unicode-range makes the browser fetch
 * only the subsets a page actually uses (latin-ext carries the ruble sign).
 *
 * JetBrains Mono (code: 400 in the landing hero and the app, 600 for bold code
 * in the app): the official v2.304 webfonts from github.com/JetBrains/JetBrainsMono,
 * SIL OFL 1.1 (../fonts/JetBrainsMono-OFL.txt). Italic stays synthesised.
 *
 * The React app links this file too (see frontend/vite.config.js). A weight is
 * only downloaded by pages that use it, so 600 costs the landing nothing.
