WCAG 2.2 AA
Accessibility
The collection is intended to be usable by keyboard, screen reader, zoom and reduced-motion users across public and protected interfaces.
What the system supports
- Keyboard operation, visible focus, skip navigation and focus-managed drawers.
- Explicit form labels, error summaries and status messages that are not conveyed by colour alone.
- Meaningful media text based on observable appearance rather than marketing copy.
- Responsive text, pinch zoom, reduced motion and layouts tested at narrow widths.
Size representations
A browser cannot know its physical scale. Stone diagrams use a bank-card calibration reference and are never labelled actual size until the reference matches.
