/* signal-dataset docs: Superpose brand skin for Furo.
 *
 * Design tokens mirrored from superpose-website/src/app/globals.css:
 * a stark, monochrome editorial look. Inter for UI and body, Source Serif 4
 * (regular weight, never bold) for headings, hairline 1px borders, 6px radius,
 * no shadows. Emerald #00bb7f is reserved for the link-hover and "live"
 * accent.
 *
 * This is a copy rather than a shared package, which is how the other doc sets
 * do it too. The copies have already drifted, so treat globals.css as the
 * source of truth when reconciling them.
