This website aims to meet the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA. Pages are built with one main heading, alternative text on images, keyboard-focus styles, link text that makes sense on its own, and body text that meets a 4.5:1 contrast ratio.

Product files are provided as PDFs and as editable documents. We are working through tagged PDFs with a clear reading order and alternative text, and each unit includes a short accessibility note. That work is ongoing.
