   ex6.click - responsive-f3e178-visuals.css
   Mobile-first canvas (320-430px), centered phone shell on wide screens.
   Every class and custom property carries the surface178d6- prefix.
   Palette anchors: #00FA9A accent / #212F3D base / #8FBC8F soft text.
   Design notes: monospace accent type over a regular Bengali body face,
   lightly rounded cards with compact buttons, mixed large + small game
   cards, short-distance transitions only, solid primary CTA paired with
   an outlined secondary CTA.
