/*
 * Prelaunch waitlist surface — a self-contained stylesheet.
 *
 * Sphere's design language, composed as a campaign page rather than an app
 * window. The black canvas dominates; one very large dotted sphere bleeds
 * off the top-right edge; the copy anchors bottom-left at scale; and the
 * only light material on the page is a single frosted, square-edged card
 * holding the waitlist. Materials and tokens come from the app's theme.css
 * (Switzer, Geist Mono for the one system label, hairlines, accent
 * #1f70c1 as live status, radius 0) — the vocabulary, not the layout.
 * Release pages keep styles.css; nothing here reaches them.
