Accessibility
The goal is a reading and browsing experience that works across devices, input methods, and individual preferences.
Structure
Pages use semantic headings, landmarks, descriptive links, and predictable navigation so they remain understandable with assistive technology.
Interaction
Interactive elements should be keyboard operable, visibly focused, and usable without relying only on color, motion, or precise pointer input.
Media
Meaningful images should include useful text alternatives. Diagrams, screenshots, captions, and video notes are reviewed for the context needed to understand them.
Ongoing review
Accessibility is treated as part of publishing quality. The site is tested during development and adjusted when an issue is discovered.
