Accessibility.

Read and explore at your own pace.

Use the skip link to reach the main content. Navigation, project filters, and demo controls support a keyboard. On smaller screens, the Menu control opens the navigation; Escape closes it and returns focus.

The theme control switches between light and dark palettes. The initial theme follows your system preference; a manual choice is saved in your browser when storage is available.

Reduced-motion preferences remove decorative animation. Main content, case summaries, and project diagrams are readable without playing a demonstration. With JavaScript disabled, original records and source explanations remain available; interactive replay and filtering require JavaScript.

Résumés and evidence.

The HTML résumé provides a readable alternative to the downloadable PDF and a print action. Project diagrams use text alongside their graphics. Each case identifies fictional data, fixed responses, and human decision boundaries.

Report a barrier.

Email achyuth.v.rachur@gmail.com with the page and the difficulty you encountered. Automated checks and keyboard testing help find issues, but do not establish formal WCAG certification or complete screen-reader coverage.
