/* 𓁹𓁹: typography, the whole of it.
 *
 * The chosen typeface is Geist, by Vercel, in two cuts:
 *
 *   Geist        prose, headings and the index, at 400 and 500
 *   Geist Mono   labels, buttons, fields and anything meant to be copied, at 400
 *
 * Both ship with the site, in `fonts/`, so no page asks another server for
 * them and the desktop app has them offline. Each cut is split by script, as
 * Google Fonts splits it, and a browser fetches a file only when the page shows
 * a character in that file's `unicode-range`: an English page loads the two
 * latin files, about 40 KB together, once. Latin comes last in each list
 * because where ranges overlap the last rule wins. Licensed under the SIL Open
 * Font License 1.1; see THIRDPARTYLICENSES.
 *
 * Every page links this file and nothing else about fonts, and nothing else in
 * the site names a font. To change the type, change this file alone: put the
 * new files in `fonts/` and list each one in `public-files.mjs`, point the
 * rules below at them, and name the families in the two tokens.
