# Dockerfile.windows
#
# Cross-compiles asyncai to self-contained PE32+ x86-64 binaries using the
# mingw-w64 toolchain. Build it from the repo root:
#
#   container build --platform linux/arm64 -m 8G -c 4 \
#     -f Dockerfile.windows -o type=local,dest=$HOME/.tmp/asyncai-win-out .
#
# The build container architecture does not affect the Windows binaries; it
# only needs to run on your machine. Use linux/amd64 on Intel hosts.
