1. Description of the Feature Request:
Converting over from #3915:

Should the background color of the notice boxes on lightmode be increased to something that contrasts more clearly with the background? Alternatively, should any other design changes be made to them? @ManonLef suggested:

I think if it were to have no background color it could look good if the left border wasn't shaped with rounding. The rounding makes it seem as if it should wrap around something.

2. Acceptance Criteria:

### Acceptance Criteria
- [ ] A decision on reached on if/which changes are needed
- [ ] If needed, any necessary changes are implemented
