One review is a claim; ten stacked five-star cards is a verdict. Density does the persuading.

Vertical 4:5 single-review spotlight ad. Background: one flat, loud brand color — [BG COLOR — e.g. "lime green"] — with a soft out-of-focus botanical shadow of palm fronds falling across it, as if sunlight is passing through leaves, giving the flat field quiet depth. Layout, all centered, top to bottom: a row of five golden stars; a big friendly bold white headline that turns the rating into a nickname, "[HEADLINE — e.g. "Five-Star Fit"]"; then the customer quote in bold white type inside quotation marks, verbatim: "[QUOTE — e.g. "I planned a beach trip just to have a reason to wear these."]", with the attribution beneath in lighter italic: "[ATTRIBUTION — e.g. "- Marcus"]". Center of frame: a large clean cutout photo of [PRODUCT — e.g. "Kavo, color-blocked printed swim trunks with a white drawcord"] floating with a soft drop shadow, the pattern doing the visual shouting. Below the product, its name in bold white: "[PRODUCT NAME — e.g. "The Mosaic Trunks"]" and a lighter subline: "[VARIANT — e.g. "Classic lined swim trunk"]". Bottom center: a lowercase white script wordmark "[BRAND — e.g. "kavo"]". Clean modern sans throughout, generous breathing room. All text razor sharp and correctly spelled, no extra review cards, no UI elements, no watermark, no people.
