A dark gothic animated sticker. A cursed gothic heart floating in the center, black and dark red colors, thick bold outline, simple shapes, high contrast. The heart slowly beats like a pulse. With each heartbeat, sharp metal thorns slightly move and tighten. At every pulse, small black bats fly out from inside the heart, then disappear smoothly. No camera movement. No background, transparent or plain dark background. Loopable animation. Sticker style, clean edges. Duration 2–3 seconds.
