[Resolve] # Forward single-label (non-FQDN) queries upstream instead of dropping # them to LLMNR/mDNS. Needed so corp shortnames like `sw-jenkins01` # (CNAME'd to `*.xsight.ent` on Pi-hole) resolve via the xsight WG bridge. # Trade-off: single-label queries now leak to whatever DNS the active # link provides — acceptable on a home/work-managed laptop, less so on # public wifi. See `man resolved.conf` → ResolveUnicastSingleLabel=. ResolveUnicastSingleLabel=yes
