[Note: this paper was never submitted to a journal, due to reasons unrelated to physics 🫠. Being posted on arXiv only is not a reflection of its quality or correctness 🙃. And of course, being published in PRL is not a guarantee of either, either 🤔.]

[It is the first time I try Zenodo. As has been promoted recently, it is an excellent practice to share numerical and experimental data for better reproducibility. We now have a way to show the raw data. But sometimes I cannot stop wondering: how can we show who did what contribution in a paper, considering the chaotic standards of authorship and sometimes corrupted academic integrity? It is ridiculous and pathetic that people lie and fool even themselves in this way. Fortunately, the joy of exploration and creativity can never be taken away.]
