Code-card emission

Emit one material through five transport-code dialects and audit mass drift.

The emit crate renders one material through five code dialects — MCNP m cards, Serpent mat cards, FLUKA COMPOUND cards, ALARA mixture blocks, and single-zone PARTISN decks — and reports a per-dialect mass-drift table with drop reasons plus re-parse verification where readers exist (MCNP, ALARA). The ARMI blueprint bridge accepts post-expansion ARMI mass-fraction keys (nU235, …) instead of GNDS names.

Try it

Pick a key dialect, edit the composition JSON, set the material name, density, and per-dialect options, then press Emit. Elemental keys, bare AM242, and unknown names fail with an inline error instead of crashing.
