Dedicated loading spinner (ICO-019): its own SVG with a @keyframes rotation and
a reduced-motion fallback (MOT-003, handled by the global reduced-motion rule in
the bundle). aria-hidden because a busy state is conveyed by the host control's
aria-busy, not by the spinner glyph. A button's loading=True mounts this.
