This crate is maintainer-facing proc-macro support for the main `kacrab` crate.
Use the public re-export from `kacrab` instead of depending on this crate
directly.

## Scope

This crate exists because procedural macros must live in a separate
`proc-macro = true` crate (a Rust compilation constraint, not a design choice).
It is not intended to be used directly; consume it through the main `kacrab`
crate's `macros` feature.

Current macro surface:

- `kafka_config!` - declares typed Kafka client config structs, builders, key
  constants, static metadata, and Java-style property parsing.

Protocol wire structs are generated by `kacrab-codegen`; this macro crate is
not the protocol generator.

## Usage

```toml
[dependencies]
kacrab = { version = "0.1", features = ["macros"] }
```

## Author

`kacrab-macros` is authored and maintained by `pirumu`.

## License

This crate is licensed under either MIT or Apache-2.0, matching the workspace.
