/* AlgoLab mobile app (components/mobile/shell.py + the mobile idea apps sip_mobile.py / ltc_mobile.py).
   Every /assets stylesheet loads on every page, so EVERY rule here starts with #mb_root: nothing leaks into
   the desktop pages. Tokens as the desktop (components/pages/theme.py): panels rgba(0,0,0,.6), chips
   rgba(255,255,255,.06), text #e8e8e8, muted #9fb3c8, headings #cfefff, accent amber #f0a030, radius 10-16px.
   Touch targets >= 44px, safe-area insets, no horizontal scroll at 360-430px, inner scrollers contain
   their overscroll (pull-to-refresh only from the header). Transitions: transform / opacity only. */
