   Lee Hyunri - layers-responsive-c70452.css
   Mobile-first lobby stylesheet for a 320-430px phone canvas.
   Design voice: humanist serif headings over a clear sans body, near-square
   "tool" corners, horizontal icon-name game bars, intro-then-section rhythm,
   restrained motion (key CTAs only), compact dual-button groups.
   Palette: #4B0082 indigo / #0F0F23 ink / #FF1493 signal pink.
