IP Emoji Pack Creator

Refer to the IP profile picture I provided as a reference for character consistency. Generate a 16-grid (4x4) emoji pack large image, with one emoji per panel, and leave a thin white border between the panels. Each character maintains the same art style, with a short Chinese text (2~6 characters, pixel font/simple black text) added at the bottom of each panel. Except for specified props, do not add complex backgrounds. No watermark, no extra characters.

The 16-cell content is: {argument name="16-cell content" default="...."}
