-# ONLY a line whose first non-blank character is `#`, and never the shebang. sh has no block-comment
-# syntax, so the only way a `#` can be something else is inside a string or a heredoc; a trailing
-# `# …` after code is left alone because the line does not START with it, and there is no heredoc
-# anywhere under root/ (grepped, and refused below in the files this loop rewrites).
-#
-# Files are matched by their shebang or by living under a shell directory (uci-defaults, keep.d),
-# never by extension — none of them have one.
