/*! cabin.css — the shared visual system for the AIMS Tesla line.
    Built for the Tesla in-car browser (17–18.5" landscape, touch, dark cabin at a
    Supercharger) and for passengers' phones. Rules that follow from that:
    - dark by default, high contrast, no pure white panels
    - every tap target ≥ 56px, text ≥ 20px on the car screen
    - one accent per app via --acc; everything else is shared
    - no hover-only affordances (touch first) */
