+Carlo: *"Nella cover scrivi T. casa, T. acqua e Temperatura esterna"*.
+
+La copertina usava le stesse stringhe della Home (`qsTr("House")`,
+`qsTr("Hot water")`): cambiarne la traduzione avrebbe cambiato **anche** la Home,
+che invece deve restare «Casa» e «Acqua calda» (sua richiesta esplicita, solo per
+la copertina). Servono quindi stringhe **proprie della copertina**:
+
+- `T. house` → italiano `T. casa`;
+- `T. water` → italiano `T. acqua`;
+- `Outside temperature %1 °C` (era `outside %1 °C`, usata solo qui) → italiano
+  `Temperatura esterna %1 °C`.
+
+Le fonti restano in inglese, come tutto il catalogo; l'italiano sta nel `.ts`.
+La Home non cambia.
