New foreground colors when BOTH "prefers-color-scheme: dark" and "prefers-contrast: more" media queries evaluate to "true" at the same time. Regular and reduced-contrast dark-mode remain unchanged, and non-dark colors continue to be browser-defaults. High-contrast dark-mode now has visually distinct visited/unvisited links for red-green and blue-yellow color blindness, and targets an even higher APCA contrast.
