Six libs: the script has four phases and write_stack alone was 342 lines
because it emits three config files from heredocs. That became three
functions, one per file, each keeping the comment that explains it -
including why settings.yml is mode 640 and not 600.
For a script whose job is writing config, "the functions still exist" is
not enough. Compared the sorted non-comment lines of the original
write_stack against its three successors: identical hash, so every line
of emitted compose, settings.yml and limiter.toml is byte-for-byte the
same and only the wrappers were added.
