Accessibility

The commitment

The site aims at WCAG 2.2 level AA. It is plain text, and the specs are Markdown that a screen reader reads as written.

What was checked

Lighthouse on the home page, 2026-11-05: Accessibility 96. Its one finding was the contrast of the theme’s credit line in the sidebar, which site: lighter search removed.

Images: no page of the site carries an image file or an image tag, so none lacks a text alternative (checked by searching every page for image tags and Markdown images, 2026-11-06). The one drawing outside the diagrams below, the tree in the Undoing Undos exhibit, is an SVG with a text label. The Composition Graph page draws two diagrams by script, and neither has a text alternative of its own; the first diagram’s edges are listed in tables on the same page, and the second diagram’s 64 edges are not.

This is not yet a full audit: one page was measured with one tool, and no screen reader or keyboard-only pass has been done.
