吞錢不見底的瓷質小豬存錢罐

Surreal conceptual product photography on a 1:1 square canvas. A blush porcelain piggy bank, plain and unmarked, stands in clean side view. Its flank is cut away and shows an impossibly deep dark shaft where a normal hollow belly should be, while the outer silhouette stays intact and readable. Blank gold coins with no markings drop through the narrow slot on top and fall in a short stream down the shaft, passing the visible base and vanishing into darkness, so nothing ever piles up. A soft rim light models the porcelain sheen and the smooth coin faces; the shaft walls fade to near-black. Palette: blush porcelain pink, deep shadow black, blank gold, soft neutral grey. The whole group is isolated on a fully transparent background with alpha = 0, not white, not colored, no checkerboard pattern, a real alpha channel. Every subject sits fully inside the frame with clear margin on all sides, and the transparency continues to every edge. Under the pig lies a soft contact shadow, semi-transparent black in the alpha channel, darkest at the point of contact and fading outward. All surfaces are plain and unmarked, with no lettering anywhere.
