Keeps this as a standalone authelia+fail2ban stack (no Frigate services).
Changes:
- docker-compose.yml: fail2ban depends_on authelia with service_healthy
condition so authelia.log exists before fail2ban tries to bind-mount it;
add inline note about pre-creating the log file
- authelia/configuration.yml: expand access_control comment block to cover
all 4 cases (added Case 3: app keeps own auth + Authelia as 2FA gate,
and Case 4: app handles auth alone); clearer per-case commented rules
- caddy/Caddyfile (replaces snippet.example.caddyfile): complete Caddyfile
with all 4 auth-case examples; (accesslog) imported in every block so
fail2ban caddy-4xx jail covers all subdomains, not just gated ones;
full inline docs for enabling Frigate proxy auth
- README.md: expand "Which sites" from 3 to 4 cases; add proxy-auth service
compatibility table (Frigate, Grafana, Gitea, Nextcloud, HA, Portainer
etc.); clarify fail2ban covers all sites via single caddy-4xx jail;
add touch authelia/authelia.log to first-run; add troubleshooting entries
for authelia.log bind-mount directory bug and fail2ban chain verification

- Pin AUTHELIA_VERSION=4.39.19 (current stable, released 2026-04-12) and
FAIL2BAN_VERSION=1.1.0-r0 in .env.example + docker-compose.yml.
- Reshape access_control.rules and the Caddyfile snippet around a
three-case decision tree: no app auth (Authelia is the gate), app with
proxy-auth support (switch FROM app login TO Authelia headers), and
apps that keep their own login (skip Authelia entirely).
- Document Frigate 0.14+ proxy auth specifically: auth.enabled: False,
proxy.header_map (remote-user / remote-groups), trusted_proxies for
the caddy_net subnet, optional X-Proxy-Secret for cross-VLAN trust.

Self-hosted SSO portal with file-based users, SQLite storage, filesystem
notifier, and an iptables-banning fail2ban sidecar. Designed to drop into
a DotheEvo-style ~/docker layout next to a dockerized Caddy on the main
server, joining the same external caddy_net so Caddy reaches Authelia by
container name. fail2ban runs in host network mode with NET_ADMIN/NET_RAW
caps so its bans hit DOCKER-USER and actually drop packets at the edge.
Includes a Caddy snippet (caddy/snippet.example.caddyfile) to merge into
the user's real Caddyfile -- this repo doesn't manage Caddy itself.
