/* ============================================================
   toolbar.css — Spartan Forge left-toolbar redesign (masterrrr)
   Two new instruments:
     1. Segmented basemap control [SAT | 3D] — replaces two
        side-by-side buttons in row1.
     2. Drawer styles for the left-side Layers panel — replaces
        the row-of-clickable-rows pattern with switches +
        slider + alternate-basemap rows.

   Inherits the existing "hunting topo" palette from forge-map.css
   (--accent, --bg-toolbar, --border, --text-bright, Barlow
    Condensed). Loads AFTER forge-map.css.
   ============================================================ */

/* ============================================================
   1. SEGMENTED CONTROL (in-toolbar, replaces SAT/3D buttons)

   Strategy: the existing two .base-btn elements are wrapped in
   a .lp-segmented track. CSS reskins them as segments. The
   underlying buttons keep their classes/IDs/handlers — so
   view-tabs.js (querySelectorAll('.base-btn')) and cesium-3d.js
   (#btn-base-3d) continue to work without rewiring.
