# Reusable workflow: verify the windows-arm64 prebuilt installs +
# loads on Windows ARM. Raku/setup-raku@v1 has no Windows ARM64
# prebuilt, so we source-build Rakudo via rakubrew inside MSYS2
# CLANGARM64 — the same MSYS2 environment we use to build the
# prebuilt. Build takes ~10-20 min on first run; cached after.
#
# Upstream notcurses-tester is broken on Windows so we don't run
# prove6 — successful zef install is what verifies the bundle.
