Isolated-netns test setup (a private tap-mess-0-0 so a second MAME can run without holding the owner's tap), the one-file/one-index TFTP servers, the trace/probe run wrappers, and the two server logs quoted in FONT_STORAGE_REPORT.md.

"""fontwork server: serve ONE chosen file for every requested name.
|
|
|
|
Used to test whether the terminal's TFTP abort is a size/capacity effect: the
|
|
same name ('69') is served as the 680-byte baseline or as a small file, and we
|
|
watch whether the transfer completes. Uses the project's own TFTPServer class.
