/* Doran FaNum (single static Regular weight) replaces Vazirmatn site-wide per user
   request. Declared across the full 100-900 weight range on purpose: this is a static
   (non-variable) face, so mapping the whole range to it means every place in this
   stylesheet that asks for a bold/heavy weight (h1-h3, buttons, etc.) still resolves to
   this one real face instead of the browser synthesizing a fake-bold — the uniform
   single-weight look was explicitly requested, not a side effect. Kept the CSS/HTML
   font-family identifier as 'Vazirmatn' rather than renaming it everywhere (dozens of
   references throughout this file and index.html) — it's just an internal label, not
   user-visible. Vazirmatn-var.woff2 is left in fonts/ unused (rollback safety) rather
   than deleted. */
