Hundreds of small circles drift outward from the center of a dark canvas, their positions updated by random angular increments each frame to create a swirling, particle-like star field. The animation uses the Canvas API’s `arc` and `fill` methods, with each particle’s color cycling through a palette of translucent blues and golds. Two mirrored points are drawn per radius, and a CSS `rotate` keyframe animation slowly spins the entire canvas, producing a hypnotic, twinkling night-sky effect.
