 * DiagScope site.
 *
 * The same look as the HTML report's light theme: cool mineral paper, deep green-black ink, teal as the one accent
 * (labels, links, command blocks, the menu), a yellow highlighter for what matters, and vermilion kept for errors
 * only. No gradients, no glow, no rounded card grid. Serif headings, a humanist sans for reading and a monospace
 * only where the content is code.
