/* Simple Host — the one shared stylesheet.
 *
 * Holds the design tokens, the base typography and the site chrome (header and
 * footer). Every page links it through the <!--sh:head--> marker, which the
 * server fills from partials/head.html; see chrome.go.
 *
 * Tokens keep the names the homepage has always used so a page's own styles
 * keep resolving. A page may still redefine a token in its own <style> while
 * its body waits to be restyled, and that must never reach the chrome, so the
 * token blocks below are applied to the header and footer elements as well as
 * to the root: the chrome reads its own copy, not the page's.
 *
 * No third-party font or script is loaded from here, or anywhere in the chrome:
 * a visitor's IP must never go to a third party. The body face is the system
 * sans stack; --mono is for code and keys only, and names JetBrains Mono first
 * only so pages that still load it keep their look.
