/**
 * Host pages sometimes ship an IE11-era CustomEvent polyfill that overrides
 * `window.CustomEvent` and forwards only bubbles/cancelable/detail — silently
 * dropping `composed`. Stencil's event emitter uses the global constructor, so
 * on such pages every internal widget event dies at the first shadow boundary
 * (observed in production at a partner: the consent "Continuar" click became a
 * silent no-op). This module restores spec-compliant behavior before the
 * widget emits anything.
 *
 * The repair only runs when the global is provably broken, and only restores
 * platform-spec behavior — a page cannot meaningfully depend on `composed`
 * being dropped.
 */
/**
 * - `healthy`: the page's constructor honors `composed`; nothing was touched.

 *   the page was left exactly as found; internal widget events may not work.
