 ## [Unreleased]
 
+### Added
+
+- Add UI-safe subpath exports `./formatters`, `./calculations`, `./constants`, and `./constants/hyperliquid` so consumers can import pure formatting/calc utilities (`perpsFormatters`, `orderCalculations`, `perpsConfig`, `hyperLiquidConfig`) without transitively loading the HyperLiquid SDK. This avoids pulling ESM-only `@noble/hashes` into CJS Jest environments where `transformIgnorePatterns` is not customized.
