   f83.click - viewport-native-e4d35d.css
   Mobile-first styles for the 320-430px canvas (centered on wide screens).
   Palette: #FFD700 gold / #FF8C00 orange / #D3D3D3 ink / #5D5D5D line / #1A1A2E base
   Visual direction: tech headings + open body, near-square corners,
   compact square game catalog, question-driven rhythm, short transitions,
   tight dual-button CTAs. Every class and custom property uses layer4d35d-.
