## Summary by CodeRabbit

- **Bug Fixes**
- Improved mobile keyboard and toolbar layout handling when the keyboard
overlays or resizes app content.
- Prevented incorrect extra spacing when Android applies keyboard insets
directly.
- Updated toolbar sizing and visibility states for smoother transitions.

- **Style**
- Adjusted mobile bottom spacing to account for keyboard height, safe
areas, and toolbar height.
