Claude Opus 5.5 in a raw API call

Create a single self-contained HTML file (inline CSS and JavaScript only; SVG and/or canvas; no external libraries, fonts, images or network requests) that plays a polished 35-second animated explainer video in the browser, like a studio motion-design piece. It plays once from start to finish and then holds on the final frame.

Topic: "How an AI model race works" — how one prompt is sent to four AI models and their results are compared fairly.

Scenes and timing (total 35 s):
1. 0-5 s: Hook. Big kinetic headline "One prompt. Four AIs." builds letter by letter; a glowing prompt card slides in.
2. 5-11 s: The prompt card splits into four copies that fly into four lanes labelled Model A, Model B, Model C, Model D.
3. 11-18 s: Each lane builds something: blocks of code stream in, a small preview window fills with a different mini artwork per lane (a wave, a chart, a planet, a city skyline), and a stopwatch per lane ticks at a different speed.
4. 18-25 s: A camera icon records each preview; the four previews line up side by side like a film strip, and one lane stalls with a friendly "error" wobble before recovering.
5. 25-31 s: Judging: score bars grow under each preview, a checklist ticks ("same prompt", "no edits", "timed", "saved"), and a folder icon swallows the four results labelled "receipts".
6. 31-35 s: Outro: all elements collapse into a single line: "Same prompt. Real receipts." and hold.

Style:
- Brand colours: deep navy background #0B1020, electric teal #19E3B1 as the main accent, warm amber #FFB547 as the secondary accent, white text.
- Clean geometric shapes, expressive easing (overshoot, staggered delays), smooth transitions between scenes (no hard blank frames), large readable text for a phone screen.
- Portrait 4:5 layout, scaled to fit the browser window and centred.
- Drive all animation from one timeline using requestAnimationFrame and performance.now; the first motion is visible within the first half second; no user interaction needed.
