   link jili - interface adaptive stylesheet (interface-adaptive-2933a7.css)
   Mobile-first lobby styles tuned for a 320-430px phone canvas that stays
   centered on wide screens. Every class and custom property carries the
   shell3a72e- prefix. Palette: #1E1E1E base, #8A2BE2 / #8B008B accents,
   #8470FF highlight. Corner language stays near-square for a tool-like feel.
