A mobile navigation menu may look simple but behave unpredictably for keyboard and screen-reader users. Focus can remain behind the overlay, close controls may be unreachable, or the menu state may not be announced.
Open the menu with keyboard activation, move through each link, close it with the visible control and Escape where appropriate, and confirm focus returns to the menu trigger. Check that the button exposes expanded or collapsed state and that background content is handled correctly while the menu is open.
