+# Canonical line-ending + diff policy for all cplieger repos.
+#
+# Normalize every text file to LF in the repository and force LF on checkout,
+# regardless of each contributor's git config. Git for Windows ships with
+# core.autocrlf=true at the system level, which otherwise rewrites the working
+# tree to CRLF on checkout and produces endless EOL-only diffs against the
+# LF-committed blobs. `text=auto` lets git detect binary files and leave them
+# untouched; `eol=lf` pins text checkouts to LF on every platform.
+#
+# Distributed to all releaseable + python repos via cplieger/ci's sync
+# workflow (see scripts/classify-repos.sh). Keep this uniform across repos;
+# repos with extra needs (e.g. homelab's age-encrypted blobs) maintain their
+# own superset and are excluded from the sync.
+
+# Force LF for all text; auto-detect and leave binary files untouched.
