When present, the option applies only to leaves whose format matches one of these; an unscoped option (this field absent) is the default for any output. A build targeting an output that matches no scoped option AND has no unscoped default is rejected with UNPRICEABLE_OUTPUT — never billed at a guessed rate (no silent fallback). Inert for non-creative vendors (signals/governance), which omit it.",
