This site targets WCAG 2.2 AA: keyboard navigation, visible focus indicators, readable contrast, meaningful alt text, honest heading structure, and touch targets of at least 44 pixels.
Animations respect your reduced-motion preference, and the 3D part viewers are supplementary; every fact shown in them is also in the page text.
