+ * German — generated by AI, and not reviewed by a native speaker.
+ *
+ * That is stated in the app as well as here, because it is the fact a reader
+ * needs in order to judge what they are looking at. Somebody told the
+ * translation is unchecked forgives an odd sentence and reports it; somebody
+ * told it was reviewed reasonably concludes the product is sloppy. The report
+ * link in Settings is the entire review process, and it only works if the app
+ * is honest about needing one.
+ *
+ * It was written against the standard terminology every German mail client
+ * already uses rather than invented, and the glossary below is the part that
+ * makes it read as one voice. But "written carefully" and "correct" are
+ * different claims and only the first is being made. The language stays marked
+ * Beta until a person who speaks German has read it and said otherwise --
+ * which is a decision somebody makes, not one a completeness percentage
+ * earns.
+ *
+ * A string missing from here renders its English source, so this file can be
+ * incomplete or wrong in places without the app breaking. Deleting an entry is
+ * a valid fix.
+ *
+ * ── Decisions this file is consistent about ──────────────────────────────
+ *
+ * Register: **Sie**, throughout. Thunderbird and Outlook use it, and ihasmail
+ * is as often a company's mail as somebody's own — "du" from a mail client
+ * that a workplace deployed reads as presumptuous in a way "Sie" never does.
+ * Where a string can avoid the question entirely it does ("Nachricht löschen?"
+ * rather than "Möchten Sie die Nachricht löschen?"), which is ordinary good
+ * German UI and sidesteps the choice; the choice is still pinned for the
+ * strings that cannot.
+ *
+ * Terminology, fixed once so it cannot drift:
+ *
+ *   Inbox           Posteingang        Archive (verb)  archivieren
+ *   Drafts          Entwürfe           Delete          löschen

+ *   Deleted Items   Papierkorb         Reply           antworten
+ *   Junk / Spam     Spam               Reply all       allen antworten
+ *   Folder          Ordner             Forward         weiterleiten
+ *   Label           Label              Star            markieren

+ * "Label" is left in English because IMAP keywords are what they are and every
+ * German mail client leaves it: translating it to "Etikett" would name
+ * something the reader cannot find anywhere else. "Spam" likewise — "Junk" is
+ * the English word Germans do not use, "Spam" is the one they do.
+ *
+ * Product names are never translated: ihasmail, Stalwart, JMAP, Sieve, vCard.
