A complete route without motion
Every map, equation, lab, and animation has a textual account. Reduced motion produces a complete static composition, and narrow screens receive a numbered prerequisite route instead of a miniature graph.
Operable controls
Navigation, menus, disclosure controls, simulations, account forms, and tutor modes are keyboard operable with visible focus. Lab controls expose labels, current values, and a live textual reading.
Review and correction
Accessibility review is an independent publication responsibility. A canonical release cannot be published without a passed accessibility record tied to the exact reviewed commit.
