/*
 * Unit E1 — the lazy 3D terrain panel. Its own file, never appended to
 * quiet-corners-maps.css or quiet-corners.css (N2/B3 territory): see the
 * commit that added it. This sheet is small and loads eagerly with the rest of
 * the dashboard's chrome, because the "3D" control button is visible on every
 * load; only the vendored themes/headlessmode/static/vendor/maplibre-gl.css
 * loads lazily, injected by Q/terrain-view.js the first time the panel opens.
 *
 * Contrast: #e4e4e7 on #0d0d1a (the dialog backdrop) is 15.4:1; the focus ring
 * below is --accent-500 #4caf63, matching quiet-corners-maps.css.
