/**
* `<lr-spinner>` — an indeterminate busy indicator. It uses non-live `progressbar` semantics so
* mounting ordinary loading UI does not announce a false status update.
*
* @customElement lr-spinner
* @slot - Optional label. `label-placement="after"` renders it and uses its live, visible
* accessible text as the progressbar name, including through forwarding slots; `none` hides it
* from both rendering and the accessibility tree.
* @csspart base - Compatibility name for the outer wrapper; use `spinner`.
* @csspart spinner - The outer wrapper. It is the same node as `base`.
* @csspart spinner-indicator - The animated indicator inside the wrapper.
* @csspart label - The accessible/visible label wrapper.
* @cssprop [--lr-spinner-size=var(--lr-size-1-25rem)] - Outer diameter of the indicator.
* @cssprop [--lr-spinner-track-width=var(--lr-border-width-medium)] - Thickness of the ring track.
* @cssprop [--lr-spinner-duration=var(--lr-transition-ambient)] - Duration/easing of one
* rotation. Not read under
*   `prefers-reduced-motion: reduce`, where the animation is disabled entirely.
* @cssprop [--track-width=var(--lr-spinner-track-width)] - Upstream-compatible track width.
* @cssprop [--track-color=var(--lr-color-brand-quiet)] - Upstream-compatible track color.
* @cssprop [--indicator-color=var(--lr-color-brand)] - Upstream-compatible indicator color.
* @cssprop [--speed=var(--lr-spinner-duration)] - Upstream-compatible rotation duration.
* @status stable
* @since 4.0.0
