I’d like to work on this issue because it combines reusable React/TypeScript UI development with practical batch-action workflows. I can implement the checkbox-based stream selection, select-all/deselect-all behavior, and batch cancel, pause, and resume actions while following the existing BULK_SELECTION_IMPLEMENTATION.md and BULK_SELECTION_VISUAL_GUIDE.md specifications. I’ll also build the confirmation flow with the selected count, handle individual transaction results so partial failures are clearly reported per stream, and ensure the implementation remains accessible, responsive, and consistent with the existing StreamsTable UI.
