Device Manager, the firewall list and the monitor name all said "punktfunk". The brand
is Punktfunk.
Renamed: the [Strings] blocks of all four driver INFs (device descriptions, install
disks, provider, manufacturer), the `description` on every SwDeviceProfile the host
creates, pf-mouse's HID manufacturer + product strings, pf-vdisplay's IddCx endpoint
friendly + manufacturer names, the EDID 0xFC display-name descriptor — so Windows now
shows `Generic Monitor (Punktfunk)` — and the netsh firewall rule names.
The EDID edit is a single byte (0x70 -> 0x50) and needs no hand-patched checksum:
Edid::generate_with already recomputes both block checksums after patching the serial.
Deliberately left lowercase, because these are IDENTITIES rather than display names and
renaming them would orphan installed state:
* the SwDeviceCreate enumerator `w!("punktfunk")` — it IS the SWD\PUNKTFUNK\... path
every pad instance id is built from
* pf-paths' `join("punktfunk")` — C:\ProgramData\punktfunk
* the CN=punktfunk-driver cert subject, which purge_driver_certs and both driver build
scripts match by string
* install.rs' `lo.contains("punktfunk virtual display")` probes, whose haystack is
to_ascii_lowercase()d, so they already match the capitalised name
Nothing is orphaned by the renames that DID happen either: netsh rule names,
Get-NetFirewallRule -DisplayName and PowerShell's -match are all case-insensitive, so
the firewall delete paths and reset-pf-vdisplay.ps1's -AdapterName / -GhostMatch
defaults still reap what every release up to 0.22.1 created.
Cosmetic, with two consequences worth knowing: it takes a driver rebuild + re-sign to
appear at all, and an existing devnode keeps its cached FriendlyName until it is
recreated.

Today's manual driver recovery (wedged under ADD/REMOVE churn → ERROR_NOT_FOUND) and the manual
host-stop/install/host-start dance around drivers/deploy-dev.ps1 are now two scripts:
* reset-pf-vdisplay.ps1 — recover a wedged driver: stop host → pnputil /remove-device the ghost
"Generic Monitor (punktfunk)" nodes → Disable+Enable the adapter
(Restart-PnpDevice doesn't exist on the box PS) → start host. No reboot
(the box boots to Proxmox). -Verify probes to confirm ADD recovered.
* redeploy-pf-vdisplay.ps1 — one-shot dev redeploy wrapping deploy-dev.ps1 with the host stop/start
(the running host holds the driver DLL) + a post-install adapter reload
(pnputil updates the store but the live device keeps the old binary).
Both standalone (don't touch deploy-dev.ps1). README gains a "Dev iteration on the test box" section.
