  "description": "60-frame composition (2s @ 30fps) with transparent background, text, and a rotating SVG icon. Output is a directory of zero-padded RGBA PNGs; the assemble path merges chunk frame directories rather than concat-copying mp4 files. renderConfig.chunkSize=15 produces N=4 chunks, exercising the per-frame state continuity across chunk seams that distinguishes the assemble path's directory-merge from mp4's concat-copy. maxFrameFailures=0 makes this a strict byte-identity gate; the upstream byte sources are Chrome's CDP screenshot output and libpng's deflate, so a Chromium or zlib bump in Dockerfile.test will produce identical pixels but different bytes — the failure mode on a Chrome version bump is 'regenerate baselines via docker:test:update', not 'investigate regression'.",
