## Summary by CodeRabbit

* **Style**
* Simplified FilterBar item layout: operator symbol now appears inline
after labels and the right-side check indicator has been removed.
  * Filter headers use bolder text weight for improved hierarchy.
* Operator badges use a lighter foreground color for better visual
contrast and consistency.
