# Third party sources

Pedal Playground by Travis Lehman is the upstream reference for the model catalog and images used in this local MVP.

- Repository: https://github.com/PedalPlayground/pedalplayground
- Cloned commit: 2594a8d6820bda8bde8a15250b7727974ac34df4
- Upstream package.json declares ISC. No standalone upstream LICENSE file was present in the cloned root.
- The reference clone, including its Git history, stays in `.upstream/pedalplayground`, which is excluded from this independent repository.
- The catalog preserves upstream dimensions in inches and their original outer-envelope meaning. Conversion to mm does not increase measurement accuracy.
- Product images and trademarks belong to their respective rights holders. Their presence in the upstream repository is not a separate grant for commercial image redistribution. This MVP keeps source records for local evaluation; check image and data use before external publication.

The Yardstomp browser editor and geometry modules are new project code. The original app is retained separately for baseline reproduction. Its advertising and analytics are not included in Yardstomp.
