A 1200x628 px price-tier comparison banner for a fictional VPN service called ShieldVault. Dark charcoal background. Three pricing card columns arranged side-by-side in a horizontal trifold layout. Left card (Basic, $3.99/mo): subdued slate border, 3 features listed in grey text. Center card (Pro, $6.99/mo): highlighted with a vivid violet border and a "Most Popular" badge arcing over the top in a curved golden ribbon — 6 features listed, two bolded in white to pop. Right card (Teams, $11.99/mo): muted gold border, 9 features. All cards share a consistent rounded-rectangle shape, white header text, feature list in smaller body text, and a CTA button at the bottom: "Start" then "Start Free" then "Contact Sales" respectively. Above the trifold: a short headline "Choose Your Shield" in bold white. All prices shown monthly with a faint strikethrough through the old price and a note "billed annually" below. Violet glow aura behind the center card draws the eye.
