Liquid Firework Effect Minigame

This is a single HTML file that implements a creative, interactive minigame in the browser. It utilizes the HTML Canvas API to render a particle system that reacts to mouse movements. Users can paint by moving their mouse, with particles emitting from the cursor. Clicking the mouse cycles through different color palettes, and pressing the spacebar clears the canvas. The particles have a firework-like appearance with glowing effects and subtle connections drawn between nearby particles. The visual style is enhanced by `mix-blend-mode: screen` for the cursor and `lighter` composite operation for particle rendering, creating a vibrant, fluid aesthetic.
