// Package memba_market_core holds the frozen, cross-engine money math and event
// schema for the Memba NFT marketplace engines. It is a PURE package (no chain/
// realm imports): split math returns values, event helpers return ordered arg
// slices, and the importing engine performs chain.Emit / banker / MarketTransfer.
//
// Constants are copied verbatim from memba_nft_market_v3 (the deployed reference).
// SplitProceeds must stay behaviorally identical to v3's splitProceeds so every
// engine pays out identically (fee/royalty conformance).
