This site — settings
Accessibility Lab
Adjust how this site looks and behaves, or try simulations of how it reads with different kinds of color vision. Whatever you set here persists across every page.
Why this exists
Accessibility settings are usually buried, and simulations usually live in separate developer tools. Putting both on one page makes it easy to check how the site holds up — and since the preferences persist, it doubles as a real settings page, not just a demo.
