Advanced AI Prompt for Interactive GPGPU Particle Systems

Act as a GPGPU Simulation Architect. Design a massive particle physics simulation for a WebGL hero section using Frame Buffer Object (FBO) ping-pong textures to store and calculate XYZ positions and velocity vectors entirely on the GPU. The system must effortlessly handle [PARTICLE_COUNT] (minimum 1,000,000) particles without dropping frames. Write a compute shader that mathematically applies an aggressive [ATTRACTION_FORCE] pulling particles toward the projected 3D mouse coordinates, active only within a strict [INTERACTION_RADIUS]. Map the output fragment colors to cycle through a [COLOR_PALETTE] gradient based directly on the velocity magnitude of each individual particle. Output both the vertex shader required for drawing the `gl.POINTS` and the fragment shader configured for additive alpha-blended glow.
