dankware carries two +DefaultRoute links (enp47s0 eth, wlan0 wifi) that
both receive the same DHCP DNS list. systemd-resolved picked a different
'current' resolver per link, so flat-name resolution flapped between the
LAN IP (192.168.0.143 via wlan0/Pi-hole) and the WAN IP (Comcast v6 via
enp47s0).
Pin 192.168.0.143 as the static IPv4 resolver on both NetworkManager
connections (ipv4.method=auto keeps the DHCP address/gateway/route,
ignore-auto-dns=yes uses only Pi-hole, ignore-auto-routes=no keeps the
DHCP routes), then restart systemd-resolved. resolved.conf's own DNS= is
a per-link fallback, so the link must be pinned.
Flat names now resolve to 192.168.0.143 on every query; apex/unknown
subdomains still fall through to Porkbun (71.227.227.172).
