/* spec-viewer-white-label-loading — NO AUTODESK BRANDING IN ANY BIMERGE VIEWER.
 *
 * The Viewer SDK (LMV 7.x) builds a loading spinner into EVERY Viewer3D it
 * constructs — headless ones included — inside `.adsk-viewing-viewer`:
 *
 *   `.forge-spinner`   the blue wheel (an <svg>) + the "Powered by AUTODESK"
 *                      image (`res/ui/powered-by-autodesk-blk-rgb.png`), the
 *                      default;
 *   `.spinner`         the bouncing-dots spinner LMV uses when
 *                      `DISABLE_FORGE_LOGO` is set (three `.bounceN` divs);
 *   `.loading-spinner` the themed variant the SDK's stylesheet paints.
 *
 * EVERYWHERE: the wheel, the logo and the dots are hidden. The spinner
 * ELEMENT itself stays where LMV puts it — LMV owns when it shows and goes
 * (inline `display` / `opacity`) — and draws a neutral ring in the app's own
 * colours instead, so a big model load (Project Home's NWD, the Explorer, the
 * dashboards, the legacy viewer) still says it is loading.
 *
 * REALITY CAPTURE: the loader is hidden outright in its three viewers — the
 * 3D pane, the 2D plan (which has its own "Loading <level>…" pill) and the
 * hilite twin. `!important` beats LMV's inline `display`.
 *
 * Linked right after the SDK's own `style.min.css` on every page that loads
 * LMV. Out of scope: the ViewCube, the toolbar and the rest of Autodesk's
 * chrome.
