river's WAN moves to a PPPoE session (Digiweb, over VLAN 10 with baby-jumbo 1508 MTU) driven by pppd, with its ip-up/ip-down hooks toggling a new wan-online.target. stream keeps its DHCP WAN, so the existing 50-wan / 50-wan-ifb networkd config moves out of routing-common into stream, and the shared consumers (ipsec, ipv6-clear-default-route) now attach to wan-online.target instead of depending on systemd-networkd-wait-online@wan directly.
