This site is built to be usable by everyone

• Semantic landmarks, one clear page heading per page, and a logical heading hierarchy.
• Full keyboard operability with visible focus states and skip-friendly navigation.
• Color is never the only carrier of meaning; evidence states and statuses also carry text labels.
• Form fields have persistent labels, and errors are announced and described in text.
• Motion respects the reduced-motion preference; interactive diagrams include text equivalents.
• Contrast targets meet WCAG 2.2 AA for text and interface elements.

The site is built with standard HTML, CSS, and JavaScript and is designed to work with current versions of major browsers and common assistive technologies, including screen readers and keyboard-only navigation.

Some dense data tables and technical diagrams are inherently complex. We provide text summaries and responsive alternatives where practical, and we continue to improve these areas. If you encounter a barrier, we want to know about it.

If any part of this site is difficult to use, contact us through the contact page and describe the page, the problem, and the technology you are using. We review accessibility reports and aim to respond promptly.
