Cute 3D App Mascot Icon Grid

Goal: Create a polished app-store mascot icon showcase featuring 40 unique cute 3D mascot icons, designed as ASO-friendly mobile app icon concepts.

Canvas: Horizontal 4:3 image on a pure black background, with a neat grid of rounded-square app icons. Use exactly 5 rows and 8 columns, evenly spaced with consistent margins. Each tile is a glossy rounded square with a soft gradient background, subtle inner glow, and soft drop shadow. No text, no labels, no watermark.

Visual style: High-end 3D clay/toy mascot style, kawaii expressions, big friendly eyes, tiny smiles, smooth rounded shapes, vibrant saturated colors, app icon lighting, soft studio shadows, crisp edges, premium iOS icon aesthetic. Every icon should feel like a distinct standalone app mascot.
