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 index-then-font server.

Serves a small (<512-byte, one-block) directory index for the font path, which
|
|
names 'evil.pcf', and serves the crafted font for that name. This isolates the
|
|
font fetch from the one-block index fetch so we can see whether a completed
|
|
multi-block font transfer parses.
