/* ──────────────────────────────────────────────────────────────────
 * Dashboard v13 — XRPL Network Pulse + World-Leading Interface
 * Iter-N+13.  Layers on top of dashboard_v11.css.
 *
 * Design notes:
 *   - Three new sections: .gn-xpulse, .gn-leading, .gn-services, .gn-devband
 *   - Same XRPL-blue → Solana-purple bias as the demo, but slightly
 *     more institutional (less cinematic glow, more density).
 *   - All motion respects prefers-reduced-motion.
 *   - WCAG-AA contrast against the cosmic dark canvas.
 * ─────────────────────────────────────────────────────────────────── */

 * Iter-N+16 — Demo Showcase strip on the dashboard.
 *
 * Surfaces all 6 cinematic /demo/<id> destinations as a state-of-the-
 * art card gallery directly on the wallet dashboard.  Visual goals:
 *
 *   - Each card has a cinematic art panel (glyph + radial glow + a
 *     hex-grid haze that animates on hover) and a content panel
 *     (tier + duration + name + subtitle + tagline + Watch CTA).
 *   - Two tiers — `flagship` and `core` — get differentiated accent
 *     colours so the eye lands on flagship demos first.
 *   - Sticky featured ring on the RWAiSE tokenisation card so the
 *     dashboard's tokenisation CTA reads "this is the entry point".
 *   - prefers-reduced-motion turns every transition + glow animation
 *     into a no-op so the strip remains legible without movement.
