 * A wide stage on surface-alt — the colour of the download panel below it —
 * with pill tabs above, round tools in its corner and a caption under it. The
 * canvas is cleared to the stage colour, so the picture has no seam; view.js
 * reads that colour, the fallback model colour and the grid colour from the
 * custom properties on the root, which keeps the palette here.
 *
 * State lives on the root as modifiers set by view.js: --js once it runs,
 * then --loading, --waiting, --ready, --error or --unsupported, plus --drawn,
 * --dragging, --armed, --toast, --fullscreen and --pseudo. Messages are
 * printed by render.php and only shown or hidden here.
