v2.2.1

Changed

• The zapper modal now fades in/out on open and dismiss (the previous animation classes were no-ops). The success view stays rendered through the fade-out: the success snapshot is now cleared when the modal opens instead of on close, so dismissing no longer flashes the empty Buy/Sell form mid-animation.
• The success view's contact CTA is now inset inside the input and renamed from "Get updates" to "Subscribe", giving the input full width.
