+I put together a [playful birthday-surprise treasure hunt](https://30cases.netlify.app/) with 30 ciphers and puzzles,
+inspired by [30 případů majora Zemana](https://en.wikipedia.org/wiki/Thirty_Cases_of_Major_Zeman).
+I vibe-coded the scaffolding and filled it with a simple personalised mix of tasks,
+and later [open-sourced the code](https://github.com/one-data-cookie/30-cases) for anyone to adapt and use.
