/*
 * Candle Shine — bundled typefaces.
 *
 * All three faces are self-hosted. Iranian visitors frequently cannot reach
 * fonts.googleapis.com reliably, so loading them from a CDN would leave the brand
 * typography broken for a large part of the audience.
 *
 *   Vazirmatn        — body / UI. Variable, 100-900. SIL OFL 1.1.
 *   Estedad          — headings. Variable, 100-900. SIL OFL 1.1.
 *   Playfair Display — Latin display accents only (latin subset). SIL OFL 1.1.
 *
 * font-display: swap keeps text visible during load; the two Persian faces are
 * preloaded from inc/setup/assets.php so the first paint already uses them.
 *
 * To swap a typeface, replace the files in assets/fonts/ and edit the src below —
 * every component reads --cs-font-sans / --cs-font-display, never a family name.
