/* Site chrome: the typeface, the shared header and the shared footer.
 *
 * homepage/build.mjs links this stylesheet into every registered page and inserts the matching markup from
 * src/shared-header.html and src/shared-footer.html, so the header and footer look and behave the same on every
 * page. Header and footer classes carry a wh- / wf- prefix (and are scoped under .site-header / .site-footer)
 * because the page stylesheets (styles.css, docs.css, markets.css, home.css) already use names like .btn,
 * .nav-links and .wrap.
 *
 * The header is laid out in a 1536-px design space: --u is one design pixel, set to 100vw / 1536 here and
 * refined by script.js to exclude the scrollbar, so the header keeps the same proportions at every desktop
 * width. Below 1100 px it switches to a fixed-size header with a menu button.
