/*
 * Self-hosted Vazirmatn — the typeface the whole site is built on.
 *
 * This is the *variable* build: a single 111 KB file that covers every weight
 * from 100 to 900, so the browser makes one request instead of four and we
 * still get real Medium/Bold/Black rather than synthetically smeared text.
 *
 * Vazirmatn covers Persian and Latin in one family, which keeps the Persian
 * and English versions of the site visually identical, and its Persian
 * numerals (۰۱۲۳۴۵۶۷۸۹) are properly drawn — system fallbacks like Tahoma
 * render them poorly, which is why shipping the font matters here.

 * Licence: SIL Open Font License 1.1 — see OFL.txt in this directory.
