/*
 * Vela — marketing site.
 *
 * Minimal on purpose: one typeface, one accent, hairlines, a lot of air. The
 * colour comes from the library itself and the feeling from motion — loose
 * screenshots gathering into an ordered wall as you scroll.
 *
 * Two themes, switched by [data-theme] on <html> (set before first paint by
 * the inline script in the head). The app window is dark in both, as the
 * product is. The brand gradient appears only in the logo and the primary
 * button.
