/**
 * com_nbradio - player skin.
 *
 * Deliberately minimal: every colour and size goes through a `--nbradio-*`
 * custom property, so a template can restyle the player without overriding
 * a single rule.
 *
 * The layout is driven by CONTAINER queries, not viewport ones - the player
 * has to fit whatever module position it is dropped into, which has nothing
 * to do with how wide the screen is. The stacked layout is the base case, so
 * a browser without container query support still gets something that fits;
 * the roomier side-by-side layout is the enhancement.
