 * Tailscale's warm stone neutrals, Inter and blue accent, tightened for a
 * productivity app: denser controls, a quieter type scale and themed browser
 * surfaces. Same ui-* class names as the root ui.css, plus productivity extras
 * at the bottom. Behaviours for the extras live in tailscale-2.js.
