/**
* Fetches and safely renders an inline HTML document. The sanitized surface establishes paint
* containment so retained author styles cannot position content over the surrounding application.
* A nonempty host `aria-label` makes the host the sole named semantic owner; otherwise the loaded
* shadow document owns the explicit-empty, `name`, or localized fallback label.
* Its passive-document profile is network-silent and non-interactive: links, form controls, and
* custom elements are unwrapped to their ordinary text/children where safe; remote navigation and
* resource attributes are removed. Images load only inline base64 GIF, JPEG, PNG, or WebP data,
* while same-document SVG fragment references may remain; an `<a>` itself never remains in the
* rendered preview.
*
* @customElement lr-html-viewer
* @event lr-render-error - Fired when fetching or sanitizing the document fails.
* @event {CustomEvent<LyraSearchChangeDetail>} lr-search-change -
*   Fired whenever search state changes. `matchCountExact=false` makes the retained count a lower
*   bound. Bubbling, composed, and non-cancelable.
* @event {CustomEvent<AnchorResultDetail>} lr-anchor-result - Fired after an `anchor` assignment or
*   `scrollToAnchor()` call is applied. `detail: { found: boolean }`. Bubbling, composed, and
*   non-cancelable.
* @event {CustomEvent<TextSelectDetail>} lr-text-select - Fired after a selection ends inside the
*   rendered document. `detail: { text: string; anchor: LyraAnchor | null; rects: DOMRect[] }`.
*   Bubbling, composed, and non-cancelable.
* @csspart base - The root container with explicit `aria-busy` loading state.
* @csspart body - The wrapper around the fetched-state content.
* @csspart html - The sanitized HTML document, once loaded.
* @csspart spinner - The visible tokenized loading treatment and ordinary text label.
* @csspart error - The error region.
* @cssprop [--lr-html-viewer-max-height=none] - Maximum block size of `[part="body"]` before it
*   scrolls internally. The `maxHeight` property sets this token inline on `[part="base"]`.
* @status stable
* @since 4.0.0
