/**
 * vcs-mapping.css
 * Styles for the VCS Mapping plugin.
 *
 * Key concerns:
 *  1. Leaflet requires a non-zero height on the container (set inline via PHP).
 *  2. z-index: 0 on the container prevents the Leaflet pane from stacking above
 *     the WP admin bar (#wpadminbar), which has z-index: 99999.
 *  3. Leaflet Routing Machine renders a panel inside the map; ensure it doesn't
 *     overflow outside the container in narrow layouts.
