The mesh is IPv6-only; the main web listener bound 0.0.0.0 only, so a
phone reaching a node over its fips0 ULA got RST on :80
(ERR_CONNECTION_ABORTED) — UI over mesh was structurally impossible.
Confirmed 2026-07-26 on framework-pt: v4:80 = 200, v6:80 = refused.
Mirror an IPv4-any main listener with a V6ONLY [::] socket on the same
port; V6ONLY so it coexists with the v4 listener regardless of
net.ipv6.bindv6only.
Also: fips.yaml generator carries the fast-reconnect profile (validated
live on framework-pt since 2026-07-24; snapshot tests updated).
