   22-bet.homes — mobile-first token sheet
   Every class and custom property carries the ui2818d- prefix.
   Palette: deep slate canvas, orange action, yellow highlight, tide accent.
   Design tone: bold light titles over light body text, softly rounded cards,
   outlined tile games, scenario-branch content rhythm, sliding focus
   indicators, solid primary + outlined secondary buttons.
