Open the linked A&R Admin test environment and navigate with the Tab key, starting with the Enter data page. Review the related frontend entry points and reproduce the missing or unclear focus states across the reported areas. Done means keyboard focus is visibly distinguishable throughout the website, especially on the Enter data page, and the behavior can be verified by keyboard navigation.
