/*
 * BattleBytes — theatre map UI (HUD, layer chips, scrubber, intel panel,
 * tooltip, overview news column, MapLibre control skin).
 *
 * Why: all chrome around the paper map is our own DOM, built by
 * static/js/theatre/theatre.js. Every colour/font comes from tokens.css so the
 * light/dark switch on :root carries through. Mobile-first: under 720 px the
 * intel panel is a 55vh bottom sheet, chips wrap, the scrubber spans the
 * width. No blinking or looping animation anywhere — only short slides.
