/**
 * Canonical sanitizer for rich article HTML rendered into a session-bearing
 * webview. Superset of the alerts and unacknowledged-bulletins variants: keeps
 * iframes and data-* attributes (renderWidgets discovers embedded sub-widgets via
 * data-*), strips scripts/inline handlers/javascript:, and forces
 * rel="noopener noreferrer" on target="_blank" anchors. When options.isAllowedIframeSrc
 * is provided, iframes whose src fails it are dropped (injected so this module
 * does not depend on /links, which owns isAllowedIframeSrc).
 * @param {string} html - Raw article HTML from the Staffbase API.
 * @param {SanitizeArticleHtmlOptions} options - Optional iframe-src allowlist.
 * @returns {string} Sanitized HTML safe to inject/parse.
