Detailed Description

struct EntropyEngine::Networking::AssetId;

Content-addressed asset identifier using SHA-256.

AssetId is a 256-bit (32-byte) hash that uniquely identifies an asset by its content. Same content always produces the same AssetId, enabling:

• Global uniqueness without central authority
• Automatic deduplication of identical assets
• Integrity verification (asset matches its ID)

Used for meshes, materials, textures, and any other asset type.
