A box called `bazzite-htpc` had no way to present itself as "Living Room" short of renaming the machine. The new knob overrides the name everywhere a human sees it: the GameStream serverinfo <hostname> element and the mDNS service instance name both adverts carry. Unset (the default) is the machine's own hostname, exactly as before. Free text is the point, so the DNS-level name is now a separate concern from the display name. The instance label may contain spaces and accents; an A-record target may not, and mdns-sd rejects the whole ServiceInfo if the target is not a legal name — which would take discovery down rather than merely look wrong. dns_label() sanitizes the target and passes an already-legal name through byte-for-byte, so hosts without the override advertise precisely what they always did. The display name loses `.` (it would split the label, and clients derive the name as the first label of the fullname, so "Ben's PC v1.2" would arrive as "Ben's PC v1") and is capped at the 63-byte DNS-SD ceiling on a char boundary.
