/*
 * styles.css — layout and surface rules.

 * THE ONE RULE THAT IS EASIEST TO GET WRONG: bands, not cards. Panels are
 * full-width bands on one continuous surface, separated by hairlines. No
 * panel has a border, a radius, or a background of its own. The only
 * card-like objects on the board are individual vehicle rows, because there
 * the card *is* the tap target.
 *
 * Designed at 412px (Pixel 8a / 10 Pro). Desktop just gets wider bands.
