+  a dialog with QR + copy/share and a `?tab=mls` link; on native it uses

+    and the converted `tokenizer.json` using SentencePiece IDs (special tokens
+    0/1/2) instead of the Marian model's `vocab.json` IDs — so `</s>` was never
+    recognized and generation looped. Rebuilt both tokenizer.json files in
