This is a preliminary, non-peer-reviewed video preprint that presents early numerical results. Author names and affiliations are fictional placeholders used for demonstration; they do not refer to real people or institutions. The results are stored outputs of an unpublished numerical study. They have not been confirmed experimentally and may change. The interactive lab, its visualisations and this text were prepared with AI assistance (Claude) and checked against the stored project files. Please do not cite these results as established findings.
