Reviewer's GuideThis PR overhauls the Robotic Arm UI to use dynamic, screen-relative sizing for improved responsiveness, refines widget styling (borders, radii, paddings, button themes), refactors the angle input dialog for auto-focus and modular helpers, and cleans up unused imports and constants.

Hey @rahul31124 - I've reviewed your changes - here's some feedback:
- In TimelineScrollView you reference
screenHeightwithout defining it — addfinal screenHeight = MediaQuery.of(context).size.height;at the top of build to avoid errors. - Extract recurring fractional sizing values (like
screenHeight * 0.026or0.083) into named constants or a helper to reduce magic numbers and improve readability. - You repeat the same border radius, padding, and side styles across multiple widgets — consider centralizing these into shared style constants or theme extensions to enforce consistency.

## Overall Comments
- In TimelineScrollView you reference `screenHeight` without defining it — add `final screenHeight = MediaQuery.of(context).size.height;` at the top of build to avoid errors.
- Extract recurring fractional sizing values (like `screenHeight * 0.026` or `0.083`) into named constants or a helper to reduce magic numbers and improve readability.

<issue_to_address>
Stat card width now depends on screen width, which may cause layout issues on very small or large screens.
Consider adding min and max width constraints to prevent the cards from becoming unusably small or large on different devices.
Suggested implementation:
```
padding: const EdgeInsets.symmetric(vertical: 4, horizontal: 2),
decoration: BoxDecoration(
```
```
decoration: BoxDecoration(
```
```
),
);
```
