## Crates

Independent Rust app crates live in this directory.

Each subdirectory should be a normal Cargo package with its own `Cargo.toml`.
The repository root is a virtual workspace, so shared commands such as `make format`, `make lint`, and `make test` run across all crates.

Suggested shape:

```text
crates/
  app-name/
    Cargo.toml
    src/
      main.rs
```
