This commit introduces several improvements to the radar visualization, focusing on responsiveness, error handling, and clearer data representation.
**Key Changes:**
* **Responsive Radar Overlay:** The persistent radar information overlay (`ift-dot-matrix` canvas) in `dom.js` is no longer a fixed size. It now dynamically adjusts its width to match the radar plot's size, ensuring a consistent visual experience across different screen resolutions and resize events. The internal drawing logic has been updated to dynamically calculate column counts based on the canvas's current dimensions.
* **Improved Error Handling in Drawing Utilities:** Comprehensive `try...catch` blocks have been added to all major drawing functions within `drawUtils.js`. This significantly enhances the application's robustness by gracefully handling potential errors during rendering, preventing crashes and providing better debugging insights.
* **TTC Category Fallback:** In `drawUtils.js`, the trajectory drawing logic for Time-to-Collision (TTC) now includes a fallback mechanism. If a track's `ttcCategory` is undefined or invalid, it will default to a neutral gray color, ensuring that trajectories are always rendered with a clear visual state.
