// hikari-components/build.rs

// in each component's StyledComponent::styles() method.
// This build script only handles the fallback case when theme styles
// are unavailable (crates.io consumption without workspace layout).

    // absent. This must also run for in-workspace builds: local path
    // consumption (the ecosystem's ~/.cargo/config.toml patch flow) has
    // ../theme/styles available, but nothing else writes these files, so a
    // missing stub used to hard-fail the build with include_str! os error 2.
