   Rais Doultana Book House — Stylesheet (Premium Edition)
   Palette lifted from the shop's own emblem, refined into a premium
   navy + gold system: deep navy primary, warm gold secondary/accent,
   on a soft ivory background. Glass panels, gradient borders and
   gold-glow shadows carry the "luxury bookstore" feel throughout.
   Display face: "Playfair Display" (editorial, high-contrast serif)
   Body face:    "Inter" (clean, modern, reads well at small size)
