webgl-particle-galaxy

A real-time particle galaxy — tens of thousands of additive-blended GPU points spiraling around a bright core, their orbits solved entirely in the vertex shader (from gl_VertexID), so the whole cloud draws in one call. Rendered as a single self-contained `index.html`. Use when the brief asks for a "particle field", "particle galaxy", "point cloud", "instanced points", "starfield", "GPU particles", or a swirling generative point system. OpenDesign serves this in powered-preview mode so the GPU stack actually runs.

# Particle Galaxy Skill

Produce a single self-contained `index.html` that renders a real-time particle system full-screen, with a clean typographic overlay on top. The signature move: **compute each particle's position on the GPU** so the CPU never loops over particles.

## Why this is a powered artifact

OpenDesign detects `getContext('webgl2')` and renders this file in **powered preview** — a cross-origin-isolated iframe with `allow-same-origin`. The full GPU pipeline is available; you do not need to work around the opaque sandbox.
