1. Source and settings
Local processing only; nothing is fetched, executed, uploaded or persisted. Each field32KiB; complete output1MiB. CPU work uses a cancellable Worker:10s startup/1s processing. Editing clears old results and exports.
Model, limits and sources
Up to 1,000 unique portable keys; JSON/YAML values must be strings. YAML accepts one flat mapping without aliases, explicit tags or duplicate keys; quote numeric/boolean-like strings. Existing strict parser is reused for simple entries; extended double quotes use JSON escapes, single quotes stay literal. No variable/command expansion; unquoted inline # is refused. This is a documented local interchange dialect, not a shell script or a universal dotenv specification. Test your receiving parser.
