 /**
- * OxiCloud - Multi-Select & Batch Actions Module
+ * OxiCloud — Batch Toolbar Module
  *
- * Adds checkboxes to grid and list views, replaces the list-view header
- * with a NextCloud-style selection bar when items are selected, and
- * provides batch delete / move / download / favorites operations.
+ * Manages the floating selection bar that appears when items are selected,
+ * and executes batch operations (delete, move, download, favorites).
+ *
+ * Selection state (_selected, handleToggleItem, selectAll, …) is kept here
+ * while the main file manager still uses its own delegation (ui.js).
+ * Once ui.js is migrated to ResourceListComponent (plan step B5), all
+ * selection mechanics will live in the component and this module will
+ * shrink to only the toolbar UI and batch-operation API calls.
