- Translate the remaining 910 strings and review the whole catalog (meaning, terms, punctuation, label length) against the screens. - Register zh-CN: any zh tag maps to it except Traditional ones (Hant, TW, HK, MO), which keep English until a Traditional catalog ships. - Hemisphere letters get their own context so the HUD sector line reads 21.33N, not a compass word; the Bhote Koshi imagery dates follow year-first languages (2021年10月16日). - cjk.css: tight tracking for Chinese text and a 9px floor on the dock voice labels and layer buttons; Latin HUD readouts keep their look. - docs/translations/zh-CN.md: style, plurals and glossary.
