+echo "$result"
+# {"status":"ok","host":"prod-server","remote_dir":"/opt/apps/element","branch":"main","containers":["element-web","synapse","postgres"],"duration_ms":4200}
+
+# Deploy con compose files adicionales y branch especifico
+result=$(docker_compose_remote_deploy "prod-server" "/opt/apps/element" "release" "docker-compose.livekit.yml,docker-compose.monitoring.yml")
+echo "$result"
+# {"status":"ok","host":"prod-server","remote_dir":"/opt/apps/element","branch":"release","containers":[...],"duration_ms":8100}

+## Notas
+
+- Flujo: verificar SSH → git pull → docker-compose pull → docker-compose up -d → listar containers.
+- La verificacion SSH usa `-o BatchMode=yes -o ConnectTimeout=5` para fallar rapido sin pedir password.
+- Los compose files adicionales se pasan como `-f file1.yml -f file2.yml` a todos los subcomandos compose.
+- `docker-compose up -d` solo recrea los servicios cuya imagen o config cambio (comportamiento nativo de compose).
+- La lista de containers al final incluye TODOS los containers corriendo en el host, no solo los del stack.
+- Requiere `jq` instalado en el host remoto para serializar la lista de containers. Si no esta, `containers` sera `[]`.
+- Los mensajes de progreso van a stderr; el JSON final va a stdout.
+- Exit code 1 en cualquier fallo (SSH, git pull, compose pull, compose up); el JSON de error NO se emite — el caller debe manejar el exit code.
+- El `host` se resuelve con `~/.ssh/config` incluyendo host, user, identityfile y puerto.
+- Diferencia con `rsync_deploy`: este flujo asume que el codigo ya esta en el remoto (via git) y usa compose. `rsync_deploy` sube archivos locales sin git.
