/**
* `<lr-skeleton>` — a loading placeholder mirroring the public Web Awesome/Shoelace skeleton
* surface under the `lr-` prefix. It is decorative by default like both upstreams; `announce`
* opts one placeholder into a localized status. An author-supplied host role remains authoritative;
* the component adds/removes `role="status"` only when it owns that opt-in role. Geometry is
* exposed as `shape`.
*
* @customElement lr-skeleton
* @csspart base - Compatibility name for the placeholder shape.
* @csspart indicator - The placeholder shape and animation surface. It is the same node as `base`.
* @cssprop [--lr-transition-ambient=1.8s ease-in-out] - Animation duration and timing function
*   shared by the pulse and sheen effects.
* @cssprop [--lr-skeleton-w=100%] - Inline size of the placeholder.
* @cssprop [--lr-skeleton-h=var(--lr-size-1em)] - Block size of the placeholder.
* @cssprop [--lr-skeleton-color=var(--lr-color-border)] - Placeholder color.
* @cssprop [--lr-skeleton-sheen-color=var(--lr-color-surface)] - Sheen highlight color.
* @cssprop [--lr-skeleton-border-radius=var(--lr-radius)] - Text/rectangle corner radius.
* @cssprop [--color=var(--lr-skeleton-color)] - Upstream-compatible placeholder color.
* @cssprop [--sheen-color=var(--lr-skeleton-sheen-color)] - Upstream-compatible sheen color.
* @cssprop [--border-radius=var(--lr-skeleton-border-radius)] - Shoelace-compatible corner radius.
* @status stable
* @since 4.0.0
