Browsers coalesce HTTP/2 connections across *.unkin.net hosts sharing the traefik-external IP. A request for a haproxy-fronted host (e.g. git.unkin.net) on a grafana connection skips SNI passthrough and hits Traefik with no HTTP router, returning 404.
- replace the TLS passthrough listener with an HTTPS listener terminating the three LE wildcards
- replace the haproxy TLSRoute with an HTTPRoute for the same hosts
- add a BackendTLSPolicy re-encrypting to haproxy:443

The haproxy edge holds its own DMZ VIP, a second public entry point alongside
traefik-external that must be firewalled and DNS'd separately. Traefik can
front it with TLS passthrough, leaving haproxy's certs and backends untouched.
- Add a `traefik-external` Gateway: HTTP :80 plus Passthrough TLS :443.
- TLSRoute the 12 `fe_https.map` hostnames to haproxy:443; HTTPRoute 301s :80.
- Make the Service ClusterIP on 443 only, releasing 198.18.199.1.
- Drop `fe_http`, `be_letsencrypt` and `fe_http.map`; certs are DNS-01 only.
Client IP now reads as a Traefik pod — the Gateway provider cannot emit PROXY protocol to a TLSRoute backend. `sessionAffinity` goes too (it would pin Traefik pods, not clients); SRVNAME cookies keep persistence.

Stalwart was only ever a test deployment. The daemon is dead on all three
backend VMs and nothing public depends on it — `unkin.net` MX points at Google —
so the edge is proxying mail to nowhere and the tcp frontends make `defaults`
emit 20 spurious HTTP-mode warnings.
- Drop the `fe_smtp`, `fe_submission`, `fe_imap` and `fe_imaps` frontends.
- Drop the five `be_stalwart_*` backends and their map entries in `fe_http.map`/`fe_https.map`.
- Drop the now-unused 25/143/587/993 Service and container ports.
`haproxy -c` on the rendered config: exit 0, 0 warnings (was 20), 0 alerts.

The au-syd1 edge proxy runs on a hand-managed LXD container outside the cluster, with no HA and no shared config source.
- Add `apps/base/haproxy/`: 3 replicas behind the DMZ LoadBalancer 198.18.199.1, config from a ConfigMap, wildcard certs from reflected secrets.
- Keep source IPs via `externalTrafficPolicy: Local`; `sessionAffinity: ClientIP` stands in for the stick-table peers a Deployment cannot name.
- Drain on shutdown: `hard-stop-after 2m`, a preStop SIGUSR1 soft-stop, 150s grace.
- Bind the stats listener to 127.0.0.1 so it is port-forward only.
- Register the app in the platform project and ApplicationSet.
