Tabular Data Converter
Deterministic conversion across CSV, JSON (array of objects), and Markdown pipe tables. RFC 4180 CSV parsing with quoted fields, embedded delimiters and newlines, optional strict type coercion, and SHA-256 digests over both input and output. First node of the client-side conversions chain with Policy Mandate and W3C VC export. Zero network.

Scope
First node of the client-side conversions chain (art-190 feeds art-191). Converts a table between three interchange formats entirely in the browser. CSV parsing follows RFC 4180 (quoted fields, doubled-quote escaping, embedded delimiters and newlines). JSON key order follows header order. Numeric strings stay text unless coerce types is enabled, and then only strict finite decimals are coerced so NaN or Infinity can never be produced. Ragged rows and duplicate headers are surfaced in warnings, never silently dropped.
