/* =============================================================================
   Rahav — Vazirmatn + Nazanin (site-wide, self-hosted)
   Applies the same Persian typeface used by the «hozor» project to the entire
   site: the WordPress theme (twentytwentyfive), the rahav-lms / rahav-support
   panels, wp-login.php and wp-admin. Loaded by the `rahav-font` must-use plugin.

   Two families are hosted next to this file and served from the site server
   (`/wp-content/mu-plugins/rahav-font/fonts/`), so no third-party CDN and no
   client-installed font is required:

   • Vazirmatn — the UI font for the whole site. It is a subset of the Vazirmatn
     variable font (weight axis 100-900) limited to the characters a Persian site
     needs, and split by unicode-range so a normal page fetches only the
     Arabic/Persian subset (~58 KB) instead of the 111 KB full family. The Latin
     subset is fetched only when Latin letters appear.

   • Nazanin — the reading font for the lesson body (`.rahav-lesson-content` only).
     Plain `@font-face`s for weights 400/700, split into Arabic/Persian, Latin and
     symbol subsets. Because it is referenced by a single class, the browser only
     downloads it on pages that actually render a lesson description.

   Nazanin — lesson body font (rahav-lesson-content)
   A Nazanin webfont for weights 400/700, self-hosted next to this file and split
   by unicode-range into Persian, Latin and symbol subsets. It is applied ONLY to
   the lesson description block so the rest of the panels keep Vazirmatn.
   `font-display: swap` is used (unlike Vazirmatn's `optional`) because the whole
   point of this face is that readers actually see Nazanin once it arrives.
