/*
 * Stars Cash Flow — premium dark UI kit (Libermall-Card system)
 *
 * Same shadcn-ui dark palette + gold primary as card.libermall.com.
 * iOS HIG-grade mechanics are kept: SF Pro typography ladder, 44pt touch
 * targets, spring easing, glass materials. Only colours move from iOS
 * systemBlue to the "premium fintech" set (gold on near-black).
 *
 * Class names match what's already used in docs/miniapp.html and
 * docs/bot-miniapp.html — .hero / .card / .btn / .seg / .tab / .pill /
 * .kpi-card / .row / .mono / .muted / .link / .badge — so the markup
 * stays untouched.
