Us vs. Them Comparison Grid Ad — Cloud Storage

A 1080x1080 px square comparison-grid ad for a fictional cloud storage startup called Vault9. The layout is a clean two-column comparison table. Left column header: Vault9 in deep teal with a small shield icon. Right column header: Other Storage in mid-grey. Five comparison rows, each row alternating between a very light teal and pure white background: Row 1 — End-to-End Encryption: green checkmark left, red X right. Row 2 — Offline Sync: green checkmark left, red X right. Row 3 — Price per TB: "$4/mo" in bold teal left versus "$12/mo" in grey right. Row 4 — Family Sharing: green checkmark both sides. Row 5 — Zero-Knowledge Policy: green checkmark left, red X right. Above the table: bold header text "Why Smart Teams Choose Vault9". Below the table: a full-width teal CTA button reading "Start Free — No Credit Card". Typography is clean Swiss International Style — Helvetica-like sans, flush left, excellent hierarchy.
