Create a self-contained HTML file with a 2D SVG animation of a California brown pelican in full breeding plumage riding a bicycle.
Requirements:
- The pelican must be clearly recognizable: large throat pouch, long orange beak, detailed feathers, webbed feet, and proper proportions.
- It should be actively pedaling (legs moving with the pedals) while holding the handlebars with its wings.
- The bicycle must have a correctly shaped diamond frame, two equal-sized wheels with visible spokes, a seat, pedals, chain, and handlebars.
- Smooth, looping animation of the wheels spinning and the pedaling motion.
- Simple background (sky, ground, optional road or coastal elements).
- Everything in one self-contained HTML file (inline SVG + CSS/JS animation, no external assets).
