/* ============================================================
   Vital Smoke Detector - funnel additions for the presell and
   interstitial exports (offer doc, "Calls to Action"):
   - a scrolling CTA bar at the top of the page that appears once
     the visitor starts scrolling, on desktop and mobile;
   - pulsating CTA buttons.
   The export stylesheets are left untouched; this file loads after
   them.
