You are a senior 3D graphics programmer with extensive experience in WebGL and Three.js.

Generate a complete, self-contained HTML file that renders a photorealistic and interactive 3D simulation of planet Earth.

The simulation must be high-quality and visually compelling, suitable for a technical demonstration or an educational tool. It should feature a detailed Earth model with distinct day/night textures, specular highlights on the oceans, and a dynamic, semi-transparent cloud layer that rotates independently from the planet to create a sense of depth and realism.

The scene must be illuminated by a directional light source representing the sun, casting realistic shadows. For example, the Earth's rotation should reveal the city lights on the night side. To enhance the scene, add a starfield background using a sphere with a star texture mapped to the inside. Implement OrbitControls to allow the user to intuitively rotate, pan, and zoom the camera for a fully interactive experience.

The final output must be a single HTML file containing all necessary HTML, CSS, and JavaScript. You can use this snippet to import Three.js:
