/* ===== CLEAN MODE: hide all visible text/UI chrome, leaving only the 3D canvas. =====
     Elements are hidden via CSS rather than removed from the DOM, so existing JS that
     references them by id (toolbar buttons, panels, badge) keeps working without errors —
     it just has nothing visible to click. Functionality (drag-to-rotate, auto-rotate,
     occipital highlight) still runs; there is simply no on-screen UI for it anymore. */
