Currently, the OutSystems UI stylesheet applies a box-shadow effect through :focus when accessibility features are enabled. As a result, the focus indicator is shown both for keyboard navigation and mouse interaction.

It would be preferable to use :focus-visible instead, so the focus indicator is only displayed when it is relevant, namely when users are navigating with the keyboard or using assistive technologies.

This would provide a more appropriate default behaviour, improving the experience for mouse users while preserving a clear and accessible focus state for keyboard navigation.
