 * RULE #4 — ADMIN FONT: Vazirmatn, bundled locally, @font-face, no external CDN.
 *
 * Every src below is a same-origin relative path. There is deliberately no
 * @import from fonts.googleapis.com, no https:// host, and no CDN reference
 * anywhere in this file. tests/Architecture/NoExternalCdnTest.php scans the
 * served CSS for external hosts and fails the build if one appears.

 * License text shipped alongside at /fonts/vazirmatn/OFL.txt
 *
 * The variable font carries weights 100-900 in a single 111KB file, so the
 * whole panel needs one font request instead of five. The static faces below
 * it are a fallback for engines without variable-font support; browsers pick
 * whichever @font-face block they can use and ignore the rest.
 *
 * Requirements 4.2, 4.3.
