 It provides ready-to-use objects for strings, numbers, identifiers, dates, coordinates, hashes, media, and collections. Validation happens when an object is created, so code receiving one of these objects can rely on its shape.
 
-Cryptographic operations are intentionally outside this package. Pigeon Swarm-specific cryptography lives in `@haskou/pigeon-swarm-crypto`; dependency direction is one-way, with the crypto package allowed to consume generic value-object representations and never the reverse.
-
 The package publishes ESM and CommonJS entry points plus TypeScript declarations. Both entry points share one runtime implementation, so class identity and NullObject configuration stay consistent when imports and requires are mixed. It does not declare a Node.js engine requirement. Identifier generation uses the installed `uuid` dependency with platform-specific Node and browser implementations.

-Cryptographic behavior is intentionally not part of this generic package. Pigeon Swarm-specific cryptography lives in `@haskou/pigeon-swarm-crypto`, which may depend on `@haskou/value-objects`; the dependency never points back from this package into Pigeon Swarm.

 The package provides separate ESM and CommonJS entry points and does not declare a Node.js engine requirement. Identifier generation delegates to the installed `uuid` dependency for Node and browser support.
