+# dotsync — sync dotfiles with the least churn.
+#
+# Deployed configs are symlinks into this repo, so `git pull` makes edits LIVE instantly
+# with no re-stow — meaning no symlink churn and no app reloads (kitty etc. keep their
+# runtime state). Re-stowing (install.sh) is only needed when files are ADDED / REMOVED,
+# to create or prune symlinks. dotsync does the minimum: pull, and re-link ONLY if the
+# pull added/removed/renamed files.
+#
+#   dotsync            pull, then relink only if the file set changed
+#   dotsync -n         preview incoming changes (fetch only; no pull, no relink)
