 * Renders the shared pending-spinner SVG used by pending-capable components.
 * Returns `nothing` when `pending` is false so callers can interpolate
 * unconditionally: `${renderPendingSpinner(this.pending, this.pendingActive)}`.
 *
 * Most consumers do not call this directly: `PendingController` (and
 * `PendingMixin`) expose `renderPendingState()`, which calls this with the
 * controller's own state. Use this directive directly only for a stateless
 * spinner without a controller.
 *
 * This is render-only and carries no design-token dependency. Pair it with the
 * shared `pending-spinner.css` style fragment, which themes the
 * `swc-PendingSpinner*` classes this emits.
 *
 * @param pending - Whether the host is in the pending (busy) state.
 * @param pendingActive - Whether the delayed busy visual is active; toggles the
 * `swc-PendingSpinner--active` class that runs the spin animation.
