2.4.7 Focus Visible

Summary

The element with keyboard focus must be visibly indicated. Without it, keyboard users cannot tell where they are and the page becomes effectively unusable. Setting `outline: none` with no replacement is the most common way this breaks.

Common failures

• Applying a global `outline: none` for aesthetics without providing a replacement focus style.
