Advanced AI Prompt for Performance-Optimized Canvas Particle Trails

Act as a WebGL/Canvas Performance Specialist. Design an elite custom cursor particle trail effect utilizing pure HTML5 `<canvas>` and vanilla JavaScript, entirely bypassing heavy DOM manipulation. You must aggressively optimize the core rendering loop utilizing `requestAnimationFrame` to guarantee a locked 60fps frame rate, even while simultaneously rendering the maximum limit of [PARTICLE_COUNT] (e.g., 200) dynamic particles. The generated particles must cycle through the hex codes defined in the [COLOR_SCHEME] palette and mathematically shrink/fade based on a strict [LIFESPAN] decay constant. Engineer a robust 'garbage collection' array-cleanup function to completely prevent browser memory leaks. Implement a structural fallback mechanism that automatically destroys the canvas context if the client device lacks hardware acceleration.
