Customize

Pick a theme that fits your eyes. The choice persists across the site — if you're going to spend time in the Lab, the playground, or reading writeups, this is the lever. Stored locally in your browser, never sent anywhere.

How this works. Each theme is a set of CSS custom-property overrides scoped to a data-theme attribute on the page root. A small bootstrap script in every page's <head> reads your choice from localStorage before the stylesheet loads, so there's no flash of the wrong palette on navigation. No JavaScript is required to render the site at any theme — the picker just writes the storage key. Source: /css/style.css + /customize/themes.js.
