/* Quarkdown Default Theme
 *
 * Override via CSS custom properties:
 * --qd-bg: background color
 * --qd-text: text color
 * --qd-accent: accent color (links, highlights)
 * --qd-heading: heading color
 * --qd-muted: muted text color
 * --qd-border: border color
 * --qd-code-bg: code block background
 * --qd-font: body font
 * --qd-font-mono: monospace font
 * --qd-max-width: content max width
 *
 * Fonts are NOT @imported here on purpose: a remote @import is fetched only
 * once this stylesheet is parsed, which serializes the requests. Link them
 * from the HTML <head> instead so they download in parallel:
 *
 *   <link rel="preconnect" href="https://fonts.googleapis.com" />
 *   <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin />
