/*
 * map.css — PathViz 2D map page styling.
 *
 * Reuses pv04.css design tokens (--pv-*). All chrome is pv04-native. The
 * map canvas itself is enforced pure black at the MapLibre style level; this
 * file just makes sure the chrome overlays don't leak light onto it.
 *
 * Layout: fixed header at top (64px, owned by pv04), full-bleed map below.
 * Overlays float on top of the map at four anchor points:
 *    - picker:  top, horizontally centered, max 720px
 *    - legend:  bottom-left
 *    - meta:    bottom-right
 *    - popup:   absolute, positioned by map.js at click site
 *    - cheats:  centered modal
 *
 * No position: fixed — the map container is position: absolute under an
 * in-flow main element so the page scrolls correctly when embedded.
