Detailed Description

ParcelError and the non-throwing surface that returns std::expected.

Throwing from_json and registry lookups remain the default. Callers that prefer a value-typed error path (a JSON parse failing for an external input, for instance) get the parallel try_* API surface that returns std::expected<cell_t, ParcelError> instead.
