Align the no-op timeline duration with the root's data-duration. The
fixture's root has data-duration="3" but the placeholder timeline tween
was still { duration: 2 } — leftover from when I bumped the duration
from 2s to 3s to dodge the PSNR-checkpoint-at-1.99s parse edge case.
The tween is a no-op (no targets, no visible effect) so rendered pixels
don't change; baseline still passes Docker regression at 100/100
checkpoints.
Reuse + efficiency reviews otherwise clean. Two findings deferred:
silence.wav duplication is real but only 2 fixtures share it today —
worth extracting to tests/_shared/ when the third fixture lands.

End-to-end Docker regression test that exercises the full variables
chain: meta.json renderConfig.variables → harness → createRenderJob →
RenderConfig → CaptureOptions → engine evaluateOnNewDocument →
window.__hfVariables → getVariables() → DOM text → rendered pixels.
Fixture (packages/producer/tests/variables-prod/):
- src/index.html: composition with three declared variables (title,
subtitle, bgColor) read via window.__hyperframes.getVariables() and
rendered as positioned text on a colored background. No animation —
keeps the regression frame-stable so it isolates "did the variables
flow through?" from motion concerns.
- meta.json: tags ["variables", "composition"] (runs in the existing
fast shard's tag filter), renderConfig.variables provides override
values the baseline reflects ("Override Title", "Override subtitle",
#0a3d62). Defaults would produce a visibly different frame, so a
failing baseline that reflects defaults means the variables didn't
propagate.
- output/output.mp4: Docker-generated baseline per the project's
CLAUDE.md golden-baseline rule.
Harness change (packages/producer/src/regression-harness.ts):
- TestMetadata.renderConfig gains an optional variables field,
validated as a JSON object in the meta.json validator.
- The createRenderJob call site forwards renderConfig.variables to
RenderConfig.variables, which the engine already consumes via
evaluateOnNewDocument (PR #600).
Verified: docker:test variables-prod passes 100/100 visual checkpoints
and audio correlation 1.000 against the committed baseline.
