   1. DESIGN TOKENS — "Mihrab" design language
   Primary: Deep Emerald | Accent: Warm Gold | Background: Warm White
   Signature element: the Mihrab Arch (used on hero media, category tiles,
   author portraits, certificates) + a fine 8-point star line pattern used
   sparingly (4-6% opacity) as ambient texture, never as decoration on top
   of text.
