Collage de Modèles de Présentation

A polished SaaS promotional collage and presentation template mosaic for [Pi], set against a clean white background in a 1:1 square canvas. The layout is arranged as a tight grid of rounded-rectangle slide thumbnails separated by thin white gutters, featuring subtle drop shadows and modern digital product aesthetics. At the center is a dominant horizontal banner with a dark rounded-square app icon on the left showing a light-blue "[Pi]" mark and diamond accent, alongside bold, crisp black text reading "[Beautiful by default. Limitless by design.]". Surrounding the central banner are 17 distinct presentation slide tiles: 1. Top-left: painterly fantasy landscape with a luminous circular ring over water and mountain peaks. 2. Top-center: dark editorial "Standards" slide with a leather strap photo and mustard-yellow title typography. 3. Top-right: purple and white "Design" slide with an illustration of a person at a laptop and geometric UI motifs. 4. Far top-right: pastel gradient "Design" title card. 5. Left-middle: monochromatic "Legacy" slide with cropped serif text and a grayscale portrait. 6. Center-middle: "Suzhou" slide with serif title, pale misty mountains, and a classical garden photo. 7.

Central banner: [Pi] logo and main slogan. 10. Far-right: dark lecture slide titled "3. Masterworks: Iconic Re…" with bulleted text and small icons. 11.
