/*
 * Filebender styles
 * =================
 *
 * Two layers, both built on the Rabbit Labs brand tokens
 * (packages/brand/rabbit-brand.css, served at /brand/rabbit-brand.css):
 *
 *   The site     the rabbitlabs.app look: dark violet ground, Space Grotesk,
 *                glowing accents (--rb-web-* tokens). Header, hero, the
 *                words around the converter, footer.
 *   The product  a clean light card (--rb-ui-* tokens, system UI font), the
 *                way rabbitlabs.app shows its extensions: the converter,
 *                results, History and Status cards, the settings dialog.
 *
 * No new hues: every colour is a brand token or a tint of one. See DESIGN.md.
