// record_mode.hpp — how much of a generator's event record to emit
//
// Shared by the generator sources so the `record` option means the same thing
// everywhere. Free of Phlex and data-model dependencies so the header-only
// Pythia8 helpers (and the standalone benchmark that shares them) can use it.
