// Cargo's build directory, kept per repo across sessions. The relative
// target resolves inside the workspace mount, so it shadows the host's
// target/ — which holds a macOS build that the container would otherwise
// rebuild from scratch every time it saw it (and rebuild again on the host
// afterwards). Plain `cargo build` finds it; no CARGO_TARGET_DIR needed.
//
// Per repo rather than shared: cargo takes an exclusive lock on a build
// directory for the duration of a build, and a differing rustc invalidates
// every fingerprint in it.
