鵜鶘騎自行車 · Claude 參考影片

Create a deterministic, 8-second looping Canvas 2D animation called “The Tidal Route”: a recognizable pelican riding a bicycle from left to right along a coastal boardwalk. 1280x720, 24 fps. Use a side-on camera with cinematic editorial illustration: desaturated teal water, dark navy shadows, warm peach dawn and a coral bicycle frame. Use a layered moving harbor backdrop, with a clear silhouette and no text.

The pelican has a long beak and visible pouch, sits on the saddle, reaches the handlebars, and pedals with both feet attached to opposite pedals. Wheels, background travel, and pedals should be mechanically coherent. Make the seam close at 8 seconds. The time argument is in seconds. Leave enough space around the bicycle to read the movement. Use only procedural drawing. No external assets, fetches, Web Audio, asynchronous code, page access, libraries, or randomness per frame.

Output only valid JavaScript defining function drawPelican(ctx, time) for an existing player that handles the canvas, preview and frame capture. Use Canvas 2D calls on ctx and local helpers inside the function. No markdown fences or explanation. Aim for 150–240 lines.
