Keyboard and structure
Pages provide a skip link, one primary heading, landmark regions, descriptive link text, visible focus, and keyboard-operable navigation.
Navigate without a pointerPublic commitment
Learning should not depend on navigating avoidable barriers.
ARCTURA aims to make its public website and learning materials usable across different devices, input methods, visual needs, and motion preferences. Accessibility is a continuing engineering and editorial responsibility.
Current implementation
Accessibility is built into the shared shell.
Responsive reading
Layouts reflow from wide screens to small devices without requiring a separate mobile site. Tables may scroll horizontally rather than truncate content.
Content survives the viewportMotion and images
Reduced-motion preferences disable nonessential transitions. Content images have descriptive alt text and essential meaning remains in HTML.
Decoration is not instructionKnown limits
Testing is meaningful only when its boundary is stated.
The current release has automated checks for headings, landmarks, metadata, alt text, link targets, intrinsic image dimensions, and shared navigation structure. It has not yet completed independent WCAG conformance evaluation or a documented test matrix across screen readers, magnification, voice input, high-contrast modes, and multiple browser/operating-system combinations.
Generated editorial artwork may contain fine visual detail that is not essential to completing a lesson. Interactive browser tools rely on native form controls and produce plain-text Markdown, but they still require broader assistive-technology testing.
Feedback
Report the barrier with enough context to reproduce it.
Open a public issue with the page URL, task you were trying to complete, browser or assistive technology when relevant, what happened, and the outcome you expected. Do not include private or sensitive information.
If a public issue is not appropriate, email learn@arctura.org. Availability and response time are not yet guaranteed; material barriers will be tracked in the repository when disclosure is safe.
Alternative access: if a learning artifact is
unusable in its current presentation, request a plain-text or
structurally simplified version and identify the affected route.
Reference
Use the current shared standard.
The conformance target is informed by the W3C Web Content Accessibility Guidelines WCAG 2.2. The standard does not endorse ARCTURA, and linking it does not establish conformance.
