Design approach
The site uses semantic headings, labelled form controls, keyboard focus indicators, a skip link, responsive layouts, text alternatives and reduced-motion support. Calculations have textual outputs and explanations. Video is optional and does not autoplay.
Current limits
Some editorial diagrams use text inside images; the same substantive steps are available as page text. Personal comparison tables may require horizontal scrolling on narrow screens.
