JSON's Data Model

JSON's grammar fits on a business card, yet it leaves several questions to implementations: how big a number may be, what a repeated key means, how to treat broken Unicode. When Node.js 2,131 writes, Python transforms and DuckDB 61,228 loads, their different answers become silent data loss.
