/*
 * Marking for AI-generated content and for attached Content Credentials.
 *
 * Lives here rather than in a site package because the markup, the icons and
 * the data all belong to this extension — a theme should be able to restyle
 * this, not be required to supply it for the marking to be legible at all.
 *
 * Sizing note: the two labelled EU icons are wide (about 3.2:1). Their height
 * is set as an HTML attribute on the element so they survive a stylesheet that
 * assumes a square, and nothing here reintroduces a fixed width.
