High-contrast theme
A pure black background with white text, brighter borders, solid header surfaces and yellow interaction colours. Focus rings become yellow and thicker so they never disappear into the page.

Choose a themeThe comfortable setting uses your browser's normal base size. Large raises the root size to 112.5%, so navigation, forms, cards and prose all scale together instead of only enlarging body copy.
Change text sizeDecorative fades, floating pieces, hover lifts, smooth scrolling and view transitions are removed. The switch follows the prefers-reduced-motion media query, so turning it on at OS level is enough.
Press Tab once after a page loads to reach “Skip to content”. Every link, button, input, select and summary shows a 3px focus ring with a clear offset. The ring follows the element's own shape.
Keyboard shortcutsPages use header, navigation, main and footer landmarks, one main heading, labelled icon buttons and hidden decorative icons. Form fields keep their visible labels, and status messages are announced where the interface provides them.
Report a barrierInformation is never carried by colour alone: game results, errors and move quality include text labels. High-contrast mode also underlines links in prose and the footer so they are distinguishable without colour.
