   opus 5 - surface-responsive-513690.css
   Mobile-first canvas tuned for 320-430px screens.
   All classes use the site prefix "shell13690-".
   Palette: #C71585 / #EE82EE / #2C2C2C / #BA55D3 / #800080
   Feel: rounded headings + compact body, near-square tool corners,
   pure image game cards, segmented CTA buttons, menu slide-in motion.
