/* Design plan
   Concept: tilework meets ticker tape. A lapis-dark market terminal framed by khatam (eight-point star) geometry.
   Colour : lapis ink backgrounds, firouzeh (turquoise) for "up" and actions, saffron for emphasis, rose-red for "down".
   Type   : Bricolage Grotesque (display), Instrument Sans (text), Vazirmatn (Persian), JetBrains Mono (data).
   Layout : full-bleed bands, one 1200px column, hero = copy + live order-book panel, everything else in calm grids. */
