 The production Docker builds install [`mold`](https://github.com/rui314/mold) and configure Rust to use it as the linker. This keeps release and profiling builds faster, especially when LTO is enabled.
 
-### cargo-sonic
-
-The Debian Docker images use [`cargo-sonic`](https://docs.rs/crate/cargo-sonic/latest) to build CPU-dispatched binaries. The image contains a baseline payload plus an optimized payload for the target architecture: `x86-64-v3` on `amd64`, and `neoverse-n1` on `arm64`.
-
-The build uses `--loader=bundle`, so the final image must include both the launcher binaries and their adjacent `.bundle` directories.
