Original animated diagrams and an explicitly labelled, arithmetically checked toy ledger. Based on arXiv:2606.02859v2. All narration and rendering are local; no paid generation. Editable source, narration audio, selectable captions, timing, font with license, and claim-linked source notes included. Revised after independent scientific and artifact critique. Checked actual export frames, ASR transcript, caption timing/layout, audio levels, encoding integrity and flashes. No end-to-end listening or continuous viewing was performed. Long reading holds and moderately dense diagrams were inspected; mechanical pacing thresholds are diagnostics. Publication awaits user approval.
