Drop stale Keycloak/OIDC, NetBird, AdGuard/.home.local, airgap, and
Prism-specific content. Reflect the current reality: single docker-compose.yml
(drasl, minecraft, mc-backup, caddy, nmsr, uptime-kuma), Drasl password-login
auth (no OIDC), public nginx+LE -> caddy ingress, DNS handled outside the repo,
FjordLauncher for guests. Point to plan/ as the source of truth; keep the
still-valid gotchas (secure-profile, authlib-injector, NeoForge pinning, mod
source) and carry-over comms prefs.
