用 Three.js 做一个从1945到2055年演变的城市街区

Build a single self-contained HTML file with Three.js that shows one city street block transforming across eras from 1945 to 2055. Add a timeline slider along the top that jumps between decades. Each era swaps the buildings, storefront signs, parked and moving cars, street furniture, trees and pedestrians, and changes the lighting mood and ambient sound effects. Use a stylized low-poly look with warm sepia tones for the post-war years, saturated neon signage for the mid-century, and clean glass and greenery for the modern and future eras. Include a small info card for the current era with a short description, plus controls for time of day, camera presets (street, aerial, free orbit) and toggles for effects. Let the user orbit with the mouse. Transitions between eras should animate smoothly rather than cut. Done means the block visibly evolves across all decades, the controls respond, and it runs by opening the file in a browser.
