+## Ejemplo
+
+```bash
+source keepass_dump.sh
+data=$(keepass_dump)
+
+# Filtrar por grupo
+echo "$data" | jq '.[] | select(.path | startswith("Servers/"))'
+
+# Solo passwords no vacios
+echo "$data" | jq '.[] | select(.password != "")'
+
+# Contar
+echo "$data" | jq 'length'
+```

+## Notas
+
+- KeePassXC 2.6.x export solo soporta `xml` y `csv` (no JSON nativo). Por eso pasamos por python3.
+- 2.7.0+ tiene `-f json` directo; este wrapper sigue funcionando.
+- Output ya descifrado (master password aplicada en export). El atributo `Protected="True"` del XML solo es marker.
+- El leading "Root" del KDBX se omite en `path`.
