## Summary by CodeRabbit

- **Style**
  - Updated styling so that opacity and transition effects apply only when a translucent background is present, enhancing visual precision.
- **Chores**
  - Renamed a data attribute in the app container for improved consistency.
  - Disabled background throttling for specific views to maintain performance when running in the background.
