+# Check every text file out with LF on every platform.

+# 44 unit test files read repository source with readFileSync and match it
+# against multi-line regexes (src/scenes/director.test.mjs,
+# src/cockpitMarkup.test.mjs, src/firstRunExperience.test.mjs, ...). Those
+# patterns anchor on \n, so under Git's default core.autocrlf=true on Windows
+# the sources check out with CRLF, every anchored pattern misses, and `npm test`
+# fails 25 checks on an unmodified clone. Normalizing here keeps the working
+# tree byte-identical on macOS, Linux, and Windows.
