Set Check

Is there a set left? A quick tool to confirm there isn't one on the board before you call it.

Take a photo of the cards, the app identifies them and answers "has set?". React and Vite on the front end, a Cloudflare Worker handling upload and analysis with OpenAI Vision behind it.

This is the second time I've built this. The first was a 2018 Python CLI that took the cards as a text file, and whose readme already listed "image upload to website" as stage three of the plan.
