all-web-solution/NebulaHeart-3D — reverse-engineered prompt

Build me a small Python project called NebulaHeart 3D. I want it to create a beautiful glowing 3D heart that feels like a space nebula, with soft colors, particles, depth, and gentle motion so it looks alive instead of static.

When I run it, it should open something local that I can actually see and interact with, like rotating the heart, zooming in and out, and watching it slowly animate. Make it feel polished and a little magical, not just a basic shape. A dark space style background would be great, and the heart should stay the main focus.

Please keep it simple to run for someone who is not very technical. I should be able to install what is needed and start it with one clear command. Add light comments and a short note on how to run it. If there is already code in index.py or catatan.py, reuse or improve it instead of starting from scratch. If you need to, look up current docs online.
