Thanks — the PR description now follows the template: summary of the one-line change, tip model (fully open source: CC0-1.0 data, Apache-2.0 code, no service or paid tier), license details, relationship (self-submission by the project's publishing account), and the checklist. All links in the entry re-verified today (site, Zenodo DOI, Hugging Face and Kaggle mirrors). Happy to adjust the wording or the placement if you'd prefer something different.
