 * HiddenCountContext — lets a hide/unhide action deep in the tree (the

 * so the "Hidden" tab appears/disappears instantly without a refetch.
 *
 * The /u/me layout provides it around its subtree. Anywhere else (home feed,
 * other users' profiles) there's no provider, so `adjustHiddenCount` defaults
 * to a no-op — hiding from those surfaces simply doesn't touch a tab that
