/* ============================================================================
   KUNDAN TRADERS — Windows & Fittings Suite
   Design world: "ANODISED"

   The palette is the material. Mill-finish aluminium is a cool grey with a
   faint blue cast; anodised champagne gold is the premium finish this shop
   actually sells. So the interface is machined graphite, and gold appears in
   exactly one place — money. Nowhere else. A tool you look at for eight hours
   earns its quality from restraint, not decoration.

   Type: Archivo (variable width — expanded reads like a machine nameplate)
         IBM Plex Mono for every number, code and dimension. Measurement, not
         costume.

   Elevation: hairline borders on the page, shadow only on things that float.
   Never both on the same element.
