 * v11647 — iPad 11-inch landscape shell regression guard
 *
 * The legacy iPad sheet changes every viewport at or below 1100px into a
 * horizontal menu. A full-screen 11-inch iPad can enter that range in Safari,
 * so keep the established desktop-like left rail for landscape only.
 * Portrait iPad, compact phones and Fold wide layouts remain untouched.
