   Prefix : every class and custom property uses "shell042fc-"
   Canvas : one 320-430px phone canvas, centered when the viewport is wider.
   Palette anchors: #004D40 / #333333 / #40E0D0 / #FAFAFA (dark = background,
   light = text). Design voice: rounded headings + compact body copy, low-corner
   zoned sections, light floating game tiles, question-driven rhythm, square
   high-contrast CTAs, micro icon-state motion only.
