Our approach
We aim to provide semantic headings, labeled controls, keyboard-operable inputs, visible focus behavior, readable contrast, responsive layouts, descriptive links, and text alternatives for meaningful graphics.
Calculator access
Results are presented as text rather than color alone. Verdict wording communicates evidence strength, limitations, and required next actions.
Known improvement work
As the diagram library grows, every instructional graphic will require an equivalent text explanation. We continue to review tables, focus order, zoom behavior, and screen-reader announcements for changing results.
