NephTox aims to conform to WCAG 2.1 Level AA. Accessibility is enforced in our build pipeline, not just aspired to: automated checks verify color contrast in both themes, keyboard reachability, and mobile layout on every change.

• Skip-to-content link and proper landmark structure on every page.
• Text colors meet the 4.5:1 AA contrast ratio in both light and dark themes, enforced by an automated CI guard.
• Full keyboard support: the command palette is a proper combobox with focus trapping and focus restore; interactive chart marks are keyboard-reachable with visible focus.
• Screen-reader support: SVG figures carry descriptive labels; data tables and heatmaps have captions, header scopes, and per-cell text alternatives; form errors and live result counts are announced; toggle states are exposed to assistive technology.
• Touch equivalents for all hover interactions; the site is tested at small viewports on every commit.

Some data visualizations (the drug-similarity map, network graph, and streamgraph) are inherently spatial and remain difficult to convey non-visually. The same underlying data is always available in accessible form: the Drug Explorer’s filterable list, each agent’s profile page, the injury atlas, and the public data API.

If you hit a barrier, please tell us via the feedback form — accessibility reports are treated as bugs and prioritized accordingly.
