// IRANYekan *fanum* maps Latin digit codepoints (0-9) to Persian glyphs.

// Montserrat (`.en`) keeps real Latin digits — so any Latin-letter run that
|
|
// also carries model numbers (HP R5, 8GB, EF2126WM…) must render under `.en`.
|
|
// Pure digit runs (e.g. "13" inside «آیفون 13 پرو») stay on the FA font and
|
|
// correctly show as Persian digits.
