html.kiosk-safe-area set background:#000 on the root element. With a root
background, body's background stops propagating to the canvas and paints
as a normal block background instead — which by CSS paint order covers
negative-z-index descendants. The dashboard/login art lives in
.bg-perspective-container at z-index:-10, so every kiosk display showed
solid black behind the UI while desktop browsers (no root background)
showed the art. Verified live on the Framework 4K TV via CDP: making the
root transparent restores the art instantly. Keep the black on body only.
