Cosmic Voyage is an interactive starfield simulation that renders a flowing field of stars with twinkling glows, drifting nebulae, and streaking comets. The visualization is driven by user controls for speed, star density, and color palettes, with a mouse-based parallax effect that shifts star positions based on distance. Built on the HTML5 Canvas API, it uses JavaScript classes for celestial objects, an animation loop with `requestAnimationFrame`, and delta-time calculations for consistent motion. All rendering is procedural, with no external data source, and the scene is dynamically generated by the main.js script.
