/**
 * Usage:
 * ```sh
 * node scripts/test-aio-a11y <origin>
 * ```
 *
 * Runs accessibility audits on several (pre-defined) pages on the specified origin. It fails, if
 * the score for any page is below the minimum (see `MIN_SCORES_PER_PAGE` below).
 *
 * `<origin>` is the origin (scheme + hostname + port) of an angular.io deployment. It can be remote
 * (e.g. `https://next.angular.io`) or local (e.g. `http://localhost:4200`).
