Protocol Buffers: The Contract and the Wire Format

Protocol Buffers are the foundation gRPC is built on — both the language you write your API contract in and the binary format your data travels as. A `.proto` file is a strict, versioned schema; the encoding is a compact, tag-based binary that's a fraction of JSON's size. Understanding both halves — the schema language and how it serializes — is what lets you design APIs that stay compatible as they evolve.
