The prompt

Double Pendulum Chaos: Two double pendulums start with a 0.001 radian difference and diverge chaotically, each drawing a fading coloured trail of its lower bob. Buttons reset, add a third pendulum, and show a live graph of the angle difference over time on a log scale. Build it as ONE self-contained HTML file: inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files); anything visual or audible is made in code (HTML/CSS, SVG, Canvas, WebGL or WebAudio). It must work when opened directly from disk, fit the browser window responsively, and run without console errors. Output ONLY the complete HTML file, starting with <!DOCTYPE html> and ending with </html>, with no explanation or markdown fences.
