D+D

Reaction model card — reduced browser build. Every value is traceable to a named source; evidence and physics fidelity are shown separately (manual §6, §36).

Definition of done (manual §36) requires independent nuclear-data and plasma-physics review before any public performance claim. This browser card is a reduced-model artifact, not a reviewed production model card.
