 *   §2  Empty states (the friendly nothing)
 *   §3  Error states (when something went wrong, with grace)
 *   §4  Celebration overlay (the moments worth a screenshot)

 *   §6  Light-theme + reduced-motion overrides
 *
 * Loaded after mobile-pages.css.  All rules respect
 * --gn-* tokens and the existing motion guards from perf-motion.css.

/* The flow:
 *   Step 1 — Welcome (brand, tagline, "Get started" CTA)
 *   Step 2 — Choose path (Create wallet vs. Import existing)
 *   Step 3 — Permissions (notifications, biometrics)
 *   Step 4 — Done (lands on Home)
 *
 * The shell takes over the whole viewport (no header, no bottom
 * nav), keeps the user focused on a single decision per screen,
 * and finishes with a celebration handoff to Home.
