柔和 3D 应用功能图标网格

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 {argument name="app category" default="general lifestyle and services"}; keep the visible Chinese labels exactly as {argument name="folder label" default="合同"} and {argument name="document label" default="摘要"} 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.
