Show a visible focus indicator

The problem

Invisible focus makes menus and controls difficult to navigate.

Practical procedure

Style :focus-visible with an outline that contrasts against dark and light cards.

Worked scenario

A three-pixel gold outline can distinguish the currently focused restart button from its neighbors.

Acceptance check

Test keyboard focus on every link, button and form field at 200% zoom.

Apply the method

Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
