   BC Game Casino - surface stylesheet (mobile-first, 320-430px canvas)
   Design voice: geometric headings over neutral body text, low-radius
   partitioned sections, grouped cover-card game tiles, question-driven
   copy rhythm, icon-only micro motion, full-width primary CTAs.
   Every class and custom property carries the surface17f13- prefix.
