Formatting without changing values
Formatting changes whitespace while preserving number tokens, escape sequences, duplicate keys, and source ordering. Comments and trailing commas fail strict JSON validation. Tree pointers escape a slash as ~1 and a tilde as ~0. Files stay under 1 MB with at most 100 nesting levels and 50,000 nodes. Combined tree pointers and row data also have a size budget, so repeated long keys may reach the limit sooner.
