Accessible product information and assessment workflows.

Current page features

• Semantic headings, landmarks and lists.
• A keyboard-visible skip link.
• Keyboard-operable navigation and disclosure controls.
• Escape-to-close and outside-click behaviour for navigation menus.
• Responsive layouts for narrow screens and high zoom.
• Reduced-motion support through the user's operating-system preference.
• Text alternatives for the main conceptual diagrams.

Assessment-interface principles

The applications should carry forward the usability lessons developed through TRACE:

• Short, direct questions with compact and consistent response controls.
• Progressive explanations that remain hidden until requested.
• Explanation pop-ups displayed above adjacent controls, closed by outside click or Escape.
• Plain-language labels before legal or technical terminology.
• Visible focus states and no reliance on colour alone.
• Keyboard access to journey nodes, variant records and scenario controls.
• Print outputs that retain structure without depending on interactive behaviour.

Known limitations

The current pages have undergone automated structural and rendering checks, but they have not completed a formal WCAG conformance audit, screen-reader testing across platforms or usability testing with disabled users. Conceptual diagrams may require further work to support complex keyboard editing in the eventual applications.
