+# The repo previously checked C#/MSBuild/XAML out as CRLF while CI shell and YAML
+# had to stay LF. That split cost more than it bought: tools that emit LF fought
+# the format gate, and a file that reached the blob with CRLF showed as modified
+# in every clone forever, which only `git add --renormalize` can clear.
