Built to be read and operated by everyone.
The site aims at WCAG 2.1 AA. This page says what that means in practice, where the limits are, and how to tell the practice about a barrier.
What is in place
Every control is reachable and operable without a mouse: the menu, the stepped diagram, the disclosure blocks, and the video. Focus is visible as a gold ring.
One heading per page at the top, landmarks for the header, navigation, main content, and footer, and a skip link to the content.
Body text at 16–17px with measured contrast above the AA floor; headings balance rather than clip; the page reflows to one column at phone width without sideways scrolling.
The one animation on the site, the flowing lines in the Dependency Mapping diagram, stops under a reduced-motion preference. Nothing moves on its own otherwise.
The three-minute overview carries captions and a transcript; the diagrams carry a text alternative, and every state they draw is also stated in prose and in a table.
Known limits
The topographic and dependency drawings are images with a single alternative text each. Their meaning is carried by the surrounding text and tables, not by the drawing.
The comparison and register tables scroll inside their own container on narrow screens. They do not reflow into cards.
The site has not been audited by a third party. "Aims at" is the honest phrase; a formal conformance claim is not made.
