/**
 * HIP-3 Deployed Dex Asset Mapping.
 *
 * Maps assets across Hyperliquid deployed dexes to their common underlying.
 * Assets with the same base name (e.g., xyz:TSLA and flx:TSLA) are auto-matched.
 * Known aliases (e.g., CL = OIL = crude oil) are explicitly mapped.
 *
 * Verified mismatches (NOT the same asset despite similar names):
 *   USAR ($17) ≠ US500 ($666) ≠ USA500 ($6646)
 *   SEMI ($319) ≠ SEMIS ($381)
 *   USOIL ($113) ≠ CL ($93)
 *   GOLDJM ≠ GOLD (different products)
 *   SILVERJM ≠ SILVER
 *   URNM ≠ URANIUM
