Accessibility

What we do

• Color contrast. The dark theme is tuned so that text, controls, and data meet AA contrast ratios against their backgrounds.
• Keyboard navigation. All interactive elements — including the calculator, links, and tables — are reachable and operable with a keyboard, with a visible focus outline and a "skip to content" link.
• Reduced motion. We respect the prefers-reduced-motion setting and disable non-essential animation for users who request it.
• Semantic structure. Pages use proper landmarks, headings, lists, and table markup so assistive technologies can convey structure and relationships.
• Responsive layout. Content reflows for zoom and small screens without loss of information or functionality.

Known limitations

Accessibility is never "done." Some third-party embeds or newer interactive features may not yet fully meet our target. Where we identify a gap, we prioritize fixing it. If something blocks you, please tell us — real reports are the fastest path to a fix.

Reporting an issue

If you encounter a barrier — anything from low contrast to a control you cannot reach with a keyboard or screen reader — let us know through the contact page. Please include the page URL, your browser and assistive technology, and a short description of what went wrong. We aim to respond promptly and to fix confirmed issues as quickly as we can.
