Proposed Changes

Adds a new floating feedback panel to the Traffic page.

Does not implement button behaviours (although hooks are in place for this and for tracks) nor does it intelligently display the panel. It can be dismissed but it will reappear on each render cycle. Button behaviours, tracks, and controlled display will be addressed in separate issues.

Why are these changes being made?

Part of the User Feedback project.

Sections (~167 bytes added 📈 [gzipped])

LGTM! However, a few styles differ from the design as my comments. Could we align with the design as much as we can?
