The previous file was saved as UTF-16 LE (FF FE BOM) and on the way
in had its UTF-8 box-drawing characters mojibake-decoded as GBK and
re-encoded, so GitLab rendered them as Chinese garbage. Rewrite the
layout tree using pure ASCII (+--, |--, \--) so no future tooling
mismatch between PowerShell ANSI/CP936 default and UTF-8 can corrupt
the file again.
