# Targets a self-hosted Windows runner inside mainland China. See README
# "Continuous integration" for runner prerequisites. Key points:
#   * github.com is unreachable here, so the checkout action is pulled from the
#     gitea.com mirror. If gitea.com is also unreachable, use the manual
#     checkout fallback below (it clones from your own Gitea instance).
#   * Flutter must be pre-installed on the runner (the dev machine). We do NOT
#     download the SDK.
#   * pub/Flutter use the flutter-io.cn mirrors; the sqlite3 native binary is
#     vendored (vendor/sqlite3/), so neither is downloaded from GitHub.
#   * The flutter_onnxruntime plugin downloads the ONNX Runtime native lib from
#     GitHub during the Windows build; we route that through the local proxy.
