/* === GIS viewer tab =========================================================
 * Layout: header (title + description + token + basemap switch) over a body
 * that splits into a left sidebar (upload button + per-file list) and a right
 * Leaflet canvas. The styling follows the GUtils house rules (slate text on
 * near-white surfaces, sky-blue interactive accents, 12-16 px corner radii).
 *
 * Leaflet's own CSS handles the map tiles and controls; this file only adds
 * the chrome around the map and tweaks a couple of Leaflet defaults (e.g. a
 * denser attribution line, the popup table styling).
