// * NO merged-mining / AuxPoW — BCH is a SHA256d standalone-parent chain.
// The header carries no aux paths; nothing BTC-specific to omit.
// * verify_pool runs SHA256d share PoW verification (NOT scrypt).
// * LevelDB storage net name: "bitcoincash" / "bitcoincash_testnet".
// * LevelDB storage net name: "bitcoincash" / "bitcoincash_testnet" / "bitcoincash_testnet4".

// This is a header-only slice (declarations only); node.cpp body lands later.
