Interactive elements
Use button elements for actions and Link components for navigation.
Icon-only buttons need aria-label.
Menu buttons should expose aria-expanded and aria-controls when controlling a child list.
Focus visibility
Focus styles must be visible in light and dark mode.
Do not remove outlines unless a replacement focus indicator is provided.
Semantic structure
Pages should use PageHeader for the main page title.
Tables should keep real table markup.
Forms should keep labels associated with visible input controls.
