 * `<rui-hover-card>` — a floating preview surfaced on hover or focus.
 *
 * Unlike `rui-tooltip`, the card can hold rich, interactive content (links,
 * avatars, buttons). It is not an APG tooltip: the panel does not use
 * `role="tooltip"` and may receive pointer and keyboard focus while open.
 *
 * Preview timing uses a shared warmup/cooldown model shared with `rui-tooltip`: the first
 * preview waits for `delay`, then subsequent previews open immediately until the post-close
 * cooldown elapses. Touch pointers open on long press.
 *
 * @element rui-hover-card
 * @attr {boolean} disabled - Suppress hover/focus preview interactions. Default: `false`.
 * @attr {string} content-label - Accessible name for the preview dialog. Default: `Preview`.
 * @fires rui-open-change - Emitted when open state changes; `detail.open`.
 * @cssclass rui-hover-card - Root wrapper.
 * @cssclass rui-hover-card__trigger - Host wrapper for the trigger.
 * @cssclass rui-hover-card__content - Floating preview surface.
