Accessibility

What we have done

• Semantic landmarks (header, main, nav, footer) on every page.
• Keyboard navigation across all interactive controls; visible focus rings.
• Sliders include aria-label, aria-valuemin/max/now, arrow-key support, +/− step buttons, and a numeric input as a non-mouse alternative to dragging.
• Reduced-motion mode (Calm Mode) suppresses non-essential animation.
• Color contrast for body text targets the AA threshold; low-emphasis text is reviewed manually.
• Modal dialogs use focus trapping, return focus to trigger on close, and support Escape to close.

Known gaps

• Independent audit by a certified accessibility reviewer is in progress; we do not yet claim conformance.
• Data visualizations on the Data Hub do not yet provide complete text-equivalent alternatives for every chart.
• Translations (Spanish, Arabic) are partial; right-to-left layout for Arabic is functional but not yet fully audited.
