Soft 3D App Feature Icon Grid

Goal: Create a clean light-neumorphic app shortcut icon set on a white background, suitable for a mobile app feature grid or homepage “king kong area”. Canvas: Wide horizontal canvas, approximately 16:9, pure white background with generous empty margins. Center the icon group horizontally and vertically with lots of whitespace. Layout: Arrange exactly 8 circular feature icons in a 4-column by 2-row grid. Use even spacing, with each icon inside a soft pastel circular disc about the same size. No titles under the icons. Icon style: Soft 3D clay/neumorphic rendering, rounded edges, glossy highlights, subtle ambient occlusion, gentle shadows, pastel gradients, miniature toy-like objects, clean commercial UI style. Each circular background should be a faint pastel gradient matching the icon color. Use high-key lighting from the upper left, no harsh outlines, no dark background. Icon count and subjects, left to right: 1. Red shopping bag with yellow rope handles on a pale pink circle. 2. Blue camera with yellow shutter button and circular lens on a pale blue circle. 3. Blue-and-white milk carton with a yellow splash graphic on a pale blue circle. 4. Purple grapes with green leaves and tendril on a pale lavender circle. 5. Faceless male professional avatar wearing a blue suit, white shirt, purple tie, and small circular badge on a pale blue circle. 6. Yellow document folder containing papers, one paper visibly labeled 「合同」, on a pale yellow circle. 7. Red gift box with yellow ribbon and bow on a pale pink circle. 8. Mint-green document sheet with checklist lines, a tab visibly labeled 「摘要」, on a pale green circle. Customization: The icon set should represent app_category; keep the visible Chinese labels exactly as folder_label and document_label if text is included. Constraints: Generate only the 8 icons described above, no extra icons, no captions, no watermark, no frame, no mockup device, no people beyond the single faceless avatar icon, and preserve the airy white composition.
