twostraws/Vortex — reverse-engineered prompt

Build me a SwiftUI particle effects package for Apple apps that feels fast and easy to drop into a project. I want it to work across iPhone, Mac, Apple TV, Apple Watch, and Vision Pro, and make it simple to show effects like rain, snow, smoke, fire, fireworks, confetti, and magic with just a few lines of code.

It should come with a set of ready made presets, but also let me create fully custom particle systems by tweaking things like where particles spawn, how fast they move, how long they live, their size, direction, and shape. Let the particles be built from simple SwiftUI views like circles, rectangles, or images, matched by tags. I also want on demand control, like triggering a burst from a button and attracting particles toward or away from a point on screen.

Please include support for multi stage effects, like fireworks that launch and then explode, plus a nice SwiftUI sandbox demo app that shows all the presets in action. Look up current Apple docs online if you need to.
