/*
 * Layout targets the Tesla browser first: a landscape panel that can be as
 * small as ~850×650 (split view next to the car visualization) or the full
 * screen. Sizes that depend on the panel (dial, pedals, cards) are set from
 * JS (see layout() in main.js); CSS avoids newer features (inset,
 * aspect-ratio, dvh) so older in-car Chromium builds render it the same.
