728x90 Leaderboard — Fintech App Promo

A crisp 728x90 px leaderboard banner ad for a fictional investment app called Vestly. Wide horizontal strip with a deep navy-to-charcoal gradient background. Left side: a translucent glassmorphism card showing a small upward-trend line chart in electric teal with a glowing halo effect, rendered at 2x pixel density. Center: bold sans-serif headline text "Invest Smarter. Start with $1." in white with the dollar sign highlighted in teal. Right side: a pill-shaped CTA button in gradient teal-to-cyan reading "Get the App", followed by a minimal app store badge row (generic icons only, no real brand marks). A subtle particle field of tiny floating dots adds depth to the dark background. The overall mood is confident and futuristic without being aggressive.
