Decisive diagnosis: OpenVPN's outbound init packets are 14 bytes with zero
replies (so MTU was never the blocker), pod UDP egress is healthy (NTP replies),
but TCP 501/443 to PIA IPs time out while Google/Cloudflare are OPEN — across many
PIA servers. This 192.168.2.x WiFi segment blackholes PIA's IP ranges (and
intercepts DNS). Not code-fixable. Reverted the port/MTU red-herring env to PIA
defaults; disabled vpn-egress pending an operator network fix (move to the
unfiltered 192.168.1.x LAN, or unblock PIA on the router). Full trace in
DECISIONS-LOG.
