/**
 * Parse untrusted HTML into a sanitized `HsonNode` tree.
 *
 * Pipeline:
 * 1. Apply the source-aware attribute pass while duplicate and reserved-name
 *    identity is still observable.
 * 2. Sanitize the normalized HTML via `sanitize_external` (DOMPurify-based).
 * 3. If sanitization removes all content (only forbidden tags/attrs),
 *    throw with a clear error message.
 * 4. Pass the sanitized HTML into `parse_html` to build the Hson tree.
 *
 * This function is the safe HTML entry-point: all external/untrusted
 * HTML should go through this path rather than `parse_html` directly.
 *
 * @param raw - Untrusted HTML string to sanitize and parse.
 * @returns A rooted `HsonNode` tree representing the sanitized markup.
 * @see sanitize_external
 * @see parse_html
