# Build environment for qroissant.
#
# Base: ghcr.io/rust-cross/cargo-xwin — Debian 13, ships with cargo-xwin,
# llvm-dlltool, and the x86_64-pc-windows-msvc rustup target preinstalled.
# We layer on nightly Rust (project uses #![feature(portable_simd)]),
# lld (so cargo-xwin can invoke lld-link), and maturin.
