Pi Presentation Template Collage

Goal: Create a polished promotional collage for {argument name="product name" default="Pi"}, showing that presentation visuals can be beautiful and varied by default. Canvas: Square 1:1 image, about 768×768 px, with a white background and a tight mosaic of rounded-rectangle presentation-slide thumbnails separated by thin white gutters. Use soft shadows, subtle bevels, and modern SaaS launch-ad aesthetics. Layout: Arrange exactly 17 visible slide tiles in an irregular grid around one dominant central banner. The central banner spans most of the width and contains a dark rounded-square app icon on the left with a large light-blue “Pi” mark and a small diamond accent, plus the bold black slogan {argument name="main slogan" default="Beautiful by default. Limitless by design."} on the right. Surround it with varied presentation templates, mixing editorial, historical, abstract, photo, and product-design styles. Visible tile count and contents: Include exactly 17 discrete tiles: 1) top-left painterly fantasy landscape with a glowing circular ring over water and mountains; 2) top-center dark “Standards” slide with a leather strap photo on the left, mustard title text, and small icon rows; 3) top-right wide purple-and-white “Design” slide with a seated laptop illustration and geometric UI decorations; 4) far top-right pastel gradient “Design” title slide; 5) left-middle black-and-white “Legacy” slide with the word partly cropped and a grayscale portrait holding an object, face obscured by a gray blur; 6) center-middle “Suzhou” slide with serif title, pale mountains, and a black-and-white classical Chinese garden photo; 7) right-middle vintage storybook “Prince:” slide with a small prince figure sitting on a planet under a starry sky; 8) far-left middle partially cropped antique mural/fresco slide with only the ending of a word visible; 9) central dominant {argument name="product name" default="Pi"} logo-and-slogan banner; 10) far-right dark lecture slide titled “3. Masterworks: Iconic Re…” with dense bullet text and small icons; 11) lower-left “Solstice” slide with soft watercolor greenery, a sun, lake, and sunflowers; 12) lower-center “Craftsmanship” slide with serif title, small circular icons, folded fabric photos, and a signature label; 13) lower-right map slide with a stylized terrain map and orange route line; 14) far-right small “Route” card with four colored square legend markers; 15) bottom-left misty karst mountain river photo tile; 16) bottom-center “3. User Experience Design” slide with paragraphs, bullet cards, and a smartphone mockup on a pale iridescent background; 17) bottom-right beige “Morandi Color System: Definition, History, and Professional Applications” slide with muted vases and botanical decor, plus a partially visible blue-purple technology slide titled “Apple Liquid G… Next-Generation Interface Design.” Visual style: The collage should feel like a premium product-launch hero image for AI presentation generation: crisp typography, high visual diversity, rounded 12–18 px corners, clean white separators, subtle depth, and a balanced mix of neutral tones, pastel purple, sage green, muted blue, charcoal, cream, and watercolor textures. Text constraints: Keep the central slogan large and fully legible. Other slide titles may be smaller but should resemble realistic presentation text. Use English text only. Do not add people outside the described slide thumbnails, do not add browser chrome, and do not include watermarks.
