   KidOS · Kiosk Shared Chassis (Direction A — "Playroom")
   ────────────────────────────────────────────────────────────
   Kiosk-specific primitives layered on top of /frontend/tokens.css.
   Include order in each kiosk html:
     <link rel="stylesheet" href="/frontend/tokens.css"/>
     <link rel="stylesheet" href="/frontend/kiosk/kiosk-common.css"/>

   Design DNA:
   - Thick sticker-black borders (2.5px)
   - Hard drop shadows (offset only, no blur)
   - Nunito Black display + Caveat handwriting accents
   - Multicolor "zones" — each kiosk mode claims one accent color
   - Mascot character + ✦ eyebrow + ticker bottom bar
