Accessibility statement
The book should remain readable without special permission, input method, or visual mode.
This website edition targets WCAG 2.2 AA. That is a design and testing commitment, not a claim of independent certification.
Applied across reading, navigation, search, tools, tables, focus states, and responsive layouts.
The edition has automated regression coverage and manual spot checks, but has not received a third-party conformance audit.
If the website reader does not fit your assistive setup, download a portable edition and use your preferred reader.
Supported by design
Access is a system, not a font-size button.
Semantic headings, landmarks, breadcrumbs, descriptive page titles, and linked section anchors.
Skip navigation, visible focus, keyboard-operable menus, search, links, controls, and reflection tools.
Responsive type, text resizing, light and dark themes, contrast-aware colors, and non-color cues.
Reduced-motion preferences disable animation and smooth transitions.
Manuscript tables include programmatic captions; narrow screens can scroll them horizontally.
HTML, EPUB, and plain-text editions provide different ways to read and adapt the work.
Known limitations
What still needs work.
- No professionally narrated audio edition is currently available.
- Long source citations and some five-column manuscript tables may require horizontal navigation at high zoom or on narrow screens.
- Support varies across EPUB applications, especially for table layout and internal navigation.
- Formal testing with a broad panel of screen-reader, switch-device, low-vision, dyslexic, and neurodivergent readers is still needed.
