"""
Asset Classification — INVARIANT characteristics only. System-wide asset universe.

Split into two axes:
  FUNDAMENTAL — intrinsic to the token's design (never changes):
    Sector*, TokenRole*, SupplyModel, Consensus, SmartContractCapability
    (* multi-label: an asset CAN belong to multiple sectors/roles)

  TECHNICAL — invariant market-structure properties (set at listing, rarely change):
    MarketCapTier, TypicalSpread/Depth, TickSize/LotSize, FeeStructure,

Plus:
  EXCHANGE — multi-exchange support:
    ExchangeProfile (per-exchange metadata), exchange-asset mapping
    (which exchanges trade which assets, with exchange-specific parameters).
    DerivativeAccess, PriceDecimals, TypicalVolume

Overlap handling (industry standard, per CoinGecko/CMC/Messari):
  - Sector & TokenRole: frozenset (multi-label). An asset can be LAYER1 + DEFI,
    or GAS + GOVERNANCE. The FIRST element is "primary" for single-label compat.
  - Consensus, SupplyModel, MarketCapTier, SmartContractCapability: single enum.
    One chain = one consensus. One supply mechanism. Inherently singular.

BIS/IMF digital asset classification, MiCA regulatory taxonomy,
academic factor models (Cong & He 2019, Harvey/Ramachandran/Santoro 2021),
