//! The ExpressLRS regulatory domain expected per region, for the ground
//! station's "ELRS domain vs region" warning (never a block: the ELRS lane's
//! regulatory authority is the RC lane's own). Names are the firmware's domain
//! names (FHSS.cpp): `ISM2G4` and `CE_LBT` at 2.4 GHz, `FCC915`, `AU915`,
//! `EU868`, `IN866`, `AU433`, `EU433` below 1 GHz. A region whose expected
//! domain was not confirmed, or that has none, maps to `None`.

/// The expected `(2.4 GHz, sub-GHz)` ELRS domains for a region row code.
