Tag meanings are brighter and slightly larger, and the top bar picks their language (Simplified/Traditional Chinese, Japanese, Korean, Russian, Spanish, French, German, Portuguese, or none) for every interface language; the old Chinese switch carries over. Typed text in any language that is not plain English is translated to English, and translating a box's foreign tags drops one whose English is already there. The backend skips DeepL for targets it does not take instead of falling back to English, and lets MyMemory detect other sources. Unused prompt helpers in translation_service.js are removed.
