Fully code-generated sci-fi title sequence: every frame and note synthesized by Opus 5.5

@prasenx shared a prompt and repo challenging a model to create a 15-second Hollywood-grade opening title sequence for an invented sci-fi film, with a fully code-synthesized soundtrack (no samples, audio files, or VSTs), every cut landing on beat, rendered at 1920x1080/60fps as a mixed MP4. Per the follow-up, Opus 5.5 delivered.

The underlying next-word repo shows a reproducible deterministic render pipeline: scene.html exposes a pure renderFrame(t), render.mjs drives headless Chromium via Playwright, screenshots each of 1800 frames, and pipes them into ffmpeg — no CSS animations or clocks, so the same code always yields the same video.
