/*
 * Machine Quotient base kit: theme, fonts and the standard navbar.
 *
 * Every standalone page on the site (anything under public/) includes:
 *
 *   <link rel="stylesheet" href="/mq/base.css">
 *   <script src="/mq/base.js"></script>
 *
 * base.js adds the MQ favicon, applies the saved theme and puts the
 * MQ navbar (brand + light/dark toggle) at the top of the page.
 * Start new pages from templates/page.html.
 *
 * The colour tokens match src/index.css (the React home page).
 * Page-specific styles go in the page's own <style> block.
 * A page can widen the navbar with  :root { --mq-width: 960px; }
