/*
 * The showcase site's stylesheet.
 *
 * The tokens are the product's, copied from apps/dashboard/src/styles.css, which took them from
 * design/generique/dashboard-generique.html (D-014, read-only). A visitor who signs up should
 * land on something that looks like the page that convinced him — so this file follows the
 * dashboard rather than inventing a second visual language.
 *
 * No framework and no dependency. The only script is `carousel.js`, and the page is complete
 * without it: the examples are a scroll-snap track that swipes and snaps with CSS alone, so the
 * script adds the automatic advance and nothing the reader would otherwise miss.
 *
 * Mobile first, like the rest: a restaurateur reads this on the phone he had in his hand.
