Take one machine's fingerprints off everyone's desktop

The audit's second tier: values that were measurements of the author's
desktop, shipped to every machine as if they were defaults.

Settings greeted every human as Gabriel; it now greets whoever
accountsservice says is signed in, and nobody when it says nothing. The
weather shipped his home coordinates and confidently reported his forecast
anywhere on earth; it now ships unset, fetches nothing until a location is
chosen, and the location row says so. The GTK bookmarks carried seven
/home/gib paths and his file server into every file dialog; they are now
generated per machine from a template and gitignored -- Nautilus edits the
instance freely, the way settings.ini already worked one file over. Web
search routed through his personal bang redirector; the engine is now the
webSearchUrl preference with a DuckDuckGo default, read by both the script
command and the suggestions extension, which the launcher-search contract
already pins to one another. The GPU vitals path defaulted to his card1 and
lost the readout on any machine enumerated differently; a machine with
exactly one GPU now adopts it. And the Containers and Snapshots pages hide
once a scan proves their backing stack absent, instead of rendering
permanently empty on machines that never had podman or snapper.

Lesser residue swept in the same pass: the DP-2 hyprpaper block one machine
needed, the author's username-typo expansions (moved to his personal seed in
user/, where personal content belongs), a capture fallback into /home/gib,
and a parity table asserting one machine's hardware as fact.
