+/// Per-tab state the browser chrome and tab ordering depend on.
+///
+/// Deliberately narrow: the whole `Map<String, TabState>` is watched by the
+/// providers feeding the always-visible quick tab switcher and the grouped tab
+/// list, so any field added here rebuilds every visible chip whenever it
+/// changes on *any* tab. High-churn fields (load progress, thumbnails, session
+/// history, find-in-page results, translation) live in per-tab notifiers in
+/// `providers/tab_detail_state.dart` instead.
