I've created a proof-of-concept implementation: **TOON Schema**

[VishalRaut2106]

📦 Repository: https://github.com/VishalRaut2106/toon-schema

This demonstrates JSON Schema 2020-12 rewritten in TOON format with:

• ✅ Complete meta-schema
• ✅ 3 real-world examples (user registration, API response, config files)
• ✅ 40-45% token savings demonstrated
• ✅ Side-by-side comparisons

Would love feedback from the community!
