/* KBhaus brand system
   Layout: navy masthead band carrying the light wordmark, then cream and
   paper sections with hairline rules. Quiet luxury: square corners,
   tracked Poppins labels, serif display, Lora body.
   Display: Circa Contrast is the brand header face; Cormorant Garamond
   stands in on the web until the licensed font file is added. */
