/*
 * Persian numerals, site-wide.
 *
 * The digit-only faces below map the ASCII digits (U+0030-0039) onto Persian
 * numeral glyphs, so every 0-9 the site prints renders as ۰-۹ without touching
 * the underlying text. Because they are declared under the *same* family names
 * the stylesheets already ask for, any rule that says `font-family: Peyda` (or
 * iranyekan, IRANSans, ...) picks them up automatically -- no per-element
 * `.fa-number` class needed, and JS-rendered numbers are covered too.
 *
 * The Peyda digits are cut from Peyda's own U+06F0-06F9 glyphs, so they match
 * the site typeface exactly. Loaded only when the locale is fa.
 *
 * Escape hatch: add class `en-number` to anything that must stay Latin.
