An accessibility toolbar on every page

Every page here now carries an accessibility toolbar, the marketing pages and the blog alike, and your choices stay in your own browser rather than being sent to us. We did not build it: it is Sienna by Benny Luk, released under the MIT licence, and it is better than anything we would have written ourselves. Thank you for making it open source. We serve it from our own domain instead of a CDN, so opening it hands your IP address to nobody and sets no cookies.

• Contrast and saturation, text size, line and letter spacing, and a dyslexia-friendly font
• Screen reader, reading guide, larger cursor, and an option to stop animations
• Settings live in your browser only. No cookies, and nothing reaches us
• Built on Sienna by Benny Luk, MIT licensed
