/* ==========================================================================
   333bed.sbs — shell-compact-813241.css
   Mobile-first canvas (320–430px). Every class carries the surface13241-
   prefix; custom properties use the same prefix.
   Palette: #FFF8DC / #F0E68C / #2C2C2C / #98FB98 / #FFFACD
   Direction: poster-style headings with narrow body text, stroke-led
   restrained rounding, grouped cover-card game shelves, fact-summary-first
   information rhythm, icon micro-motion only, staggered primary/secondary
   CTA buttons. Navigation: two-layer top bar (brand row + action row),
   sectioned drop-down menu sheet, compact fixed bottom icon rack with
   label-emphasised active state and short vertical-lift press feedback.
