Please don't add new translations unless you really really need to. (claude loves to add new ones) Most of these should be swappable with existing ones. The %q approach makes it easy adapt a message for your use.

Will do. Pushed cd142d5 — all 11 custom strings collapsed into existing pot entries (Invalid %q pin, %q init failed, DAC Device/Channel Init Error) and the redundant in-driver deinit check is gone (shared-bindings check_for_deinit already covers it). Net: zero new pot entries vs main.
