A humorous and conceptual illustration showing a floating smartphone wrapped in flowing, liquid sealing wax. A large, ornate brass stamp is pressing onto the screen, sealing a text message bubble. The art style is abstract and rounded, resembling soft clay modeling or vector art. The color palette is strictly monochromatic royal blue. Highlights are pale blue, and shadows are deep navy, creating a monochromatic depth. The wax splashes are shaped dynamically, contrasting the rigid rectangular phone. No photorealism; emphasize smooth curves and stylized forms.
