+    recalling each codepoint from training, which is unreliable for long
+    CJK strings — the model regularly emits the wrong codepoint (e.g.
+    writes `\u3103` thinking it is 管 U+7BA1, but `\u3103` is
+    actually ㄃, so the user sees `管理工具` rendered as `㄃3用箱`).
+    The trigger is long, multi-line questions with hundreds of CJK
+    characters: that is exactly when reflexive escaping kicks in and
+    exactly when miscoding is most damaging. Long ≠ escape. Keep
+    characters literal.
