## Summary by CodeRabbit

* **New Features**
* Improved URL paste: text is split into segments, inserted correctly,
and single-URL pastes create linked-page references.

* **UI Improvements**
  * Redesigned layout selector with compact dynamic options.
* Number-format options are always available in table headers and mobile
menus.

* **Bug Fixes**
  * More consistent paste behavior for mixed text+URL content.
  * Prevented recursive selection updates when exiting edit mode.

* **Tests**
* Added tests for URL splitting, paste insertion, number formatting, and
selection behavior.

* **Chores**
* Removed number-formatting feature flag; formatting now applied by
default.
