/* =========================================================
   Rayan Coffee — Digital Menu
   Design tokens (from brief):
   - Dark coffee-bar surfaces, warm gold accent, soft glass cards.
   - Type: Vazirmatn across the page — a single well-crafted Persian
     variable font gives every weight we need (light body copy through
     the heavy display weight for the hero) without stitching together
     mismatched Farsi faces.
   - Signature element: a thin gold "pour ring" glow — echoing the
     circular latte-art mark in the Rayan logo — placed behind the
     hero logo and repeated softly behind category art.
   ========================================================= */
