This matches more the text that we use elsewhere. This might be too close to the green used by "server" now.

There was a problem hiding this comment.
This ensures that we blend onto gray instead of mixing colors.

… hovered (#34881) Stacked on #34880. In #34861 I removed the highlight of the real view when hovering the timeline since it was disruptive to stepping through the visuals. This makes it so that when we hover the timeline we highlight the rect with the subtle hover effect added in #34880. We can now just use the one shared state for this and don't need the CSS psuedo-selectors. <img width="603" height="813" alt="Screenshot 2025-10-16 at 3 11 17 PM" src="https://github.com/user-attachments/assets/a018b5ce-dd4d-4e77-ad47-b4ea068f1976" />

The selection is now clearer with a wider outline which spans the bounding box if there are multi rects.
The color now gets darked changes on hover with a slight animation.
The colors are now mixed from constants defined which are consistently used in the rects, the time span in the "suspended by" side bar and the scrubber. I also have constants defined for "server" and "other" debug environments which will be used in a follow up.
