Three.js程序化机场：滑行的客机与地勤车辆

Build a procedural airport simulation in Three.js, delivered as one self-contained HTML file with no external assets. Model everything in code: a tarmac apron, a runway with markings, grass surroundings, a glass terminal with a control tower, and airliners with blue-and-white liveries. Add working ground traffic such as a fuel tanker, baggage carts, tugs and small figures of ground crew moving around parked aircraft, and let planes taxi, take off and land on a loop. Provide several automatic camera views (gate level, runway end, wing close-up, tower view) that cut between each other, with soft daylight and a pale sky. Keep the style clean and slightly low poly. Done means the scene runs smoothly, vehicles and aircraft move without clipping, and the cameras show the whole airport cycle.
