 * Link — interactive navigational atom.
 *
 * Pattern B (atom-interactive): renders its own `<a>` (or `<button>` when no
 * `href` is set) inside shadow DOM.
 *
 * The component honors the **DESIGN.md "Visited Magenta Rule"** — `:visited`
 * anchors flip to `#aa18ce` (`color.text.brand.visited`). When `target="_blank"`
 * is set, `rel="noopener noreferrer"` is auto-applied and a small external-link
 * indicator is rendered after the label unless the consumer explicitly opts out
 * via `external="false"`.
 *
 * @element mud-link
 *
 * @slot - (default) The link label content. Plain text or rich inline content.
 * @slot icon-start - Optional leading `mud-icon`.
 * @slot icon-end - Optional trailing `mud-icon` (suppressed when the auto
 *                  external-link indicator is rendered to avoid duplication).
