- Shift rail by half-thumb and shrink by thumb size (H/V)
- Size track using thumb center (width = thumb.x, height = thumb.y)
- Clamp thumb position against parent size instead of root
- Visual fill now matches interaction range
- Apply consistently to Cosmic, Cupertino, Fluent, Material
- Note: Qt backend not updated; still misaligned
