This package runs on the host with `std` and `f64`. It derives gamut matrices
and transfer LUTs and emits Rust `const` tables with `MAX_ERR_LSB`. It is
never linked into a target firmware build.

```toml
[dependencies]
ph-color-bake = "0.1"
```

MSRV is Rust 1.94.0, edition 2024. This package requires `std` and uses `f64`;
it is host tooling and must not be linked into target firmware.

The binary emits `Matrix3` and `InterpLut` `const` source on `--emit-rust`,
including sRGB OETF/EOTF tables. `--emit-oklab-module` emits the checked-in
Oklab matrix and cube-root LUT module, while `cargo xtask generate` writes that
artifact through the repository workflow. `--emit-golden` writes frozen CSV
vectors under `crates/color/tests/golden/`.

```sh
ph-color-bake --emit-rust
ph-color-bake --emit-oklab-module
```
