# Unified code style for OpenNest.
# Canonical formatter: CSharpier (see .config/dotnet-tools.json).
#   dotnet tool restore
#   dotnet csharpier check .    # verify before committing
#   dotnet csharpier format .   # fix
# These settings match CSharpier's conventions so IDE auto-formatting
# (VS / Rider / VS Code) stays consistent with the formatter.
