# the stock clang on noble (18) is too old for the 2025+ MSVC STL that
# cargo-xwin downloads (yvals_core.h: "error STL1000: expected Clang
# 19.0.0 or newer"), so take a newer clang toolchain from apt.llvm.org.
# apt.llvm.org sometimes half-publishes a new version, in which case the
# unversioned meta packages become uninstallable ("clang: Depends:
# clang-NN ... not installable"); so pick the newest versioned set that
# actually resolves (a dry-run checks the whole dependency closure) -
# nothing is hardcoded, this tracks the newest working release.

# found further down PATH; all other invocations pass through
# untouched, and tools with other names (clang-cl, lld-link) are not
