   The Lens: shared stylesheet
   Identity v1.1: Dark Charcoal + Warm Taupe, Visby CF + Cormorant Garamond,
   "Look closer." Belleza stands in for Visby CF until the licence is in place;
   swapping it is the --font-primary line plus one @font-face.

   Contrast rule: accents are lighter on dark and darker on light. Warm Taupe
   (#C2A882) is for text on charcoal only (7.2:1). On cream, accent text uses
   --accent-on-light (5.5:1); plain taupe on cream is 2.9:1 and is decoration only.
