Accessibility

Accessibility is part of evidence clarity.

Minimum requirements

• WCAG 2.2 AA contrast for text and controls
• visible keyboard focus
• complete keyboard operation
• reduced-motion support
• labels for color-coded states
• scalable text without clipped chamfers
• graph alternatives for non-visual users

Glow and transparency

Glow never replaces a boundary. Glass never reduces text contrast below requirements.

Data visualization

Every chart or graph requires:

• textual summary
• accessible labels
• keyboard navigation when interactive
• state information that does not depend only on color
