Sunset and Sunrise Mountains
This example shows an animated day/night cycle over a mountain landscape, with a sun and moon that alternate positions and colors while the sky and terrain shift between daylight and nighttime palettes. The scene uses SVG gradients and paths to render the terrain, with JavaScript controlling state-based color transitions and toggling animated birds during the day and wolves at night. Static night mode introduces randomized lightning strikes and a flashing white overlay. The code uses DOM manipulation with `getElementById`, `querySelectorAll`, and the Web Animations API pattern of `setTimeout` for timed effects, while sound elements are triggered via HTML5 audio.
