Minify JSON for Production Payloads
Remove every unnecessary byte before shipping: minification strips all insignificant whitespace while preserving the exact data structure, verified by a re-parse before output is shown.
Ideal for config files embedded in HTML, API responses, and fixture files. Runs locally — nothing uploaded.
