 - Use Traditional characters and consistent terminology from the glossary below. Prefer short, neutral instructions: 「點選地圖」、「儲存金鑰」.
 - Use full-width Chinese punctuation and 「」 for quotations. Keep `·`, `…`, provider names, codes and placeholders unchanged.
 - Separate Chinese from Latin letters and numbers with a space: 「AIS 船舶」、「24 小時」. Keep unit symbols unchanged: km, m, km/h, m/s, kn, ft, MW, °, %.
+- Relative-time placeholders may already include 前. In `LIVE · updated {age}`, the caller supplies the complete relative age; do not append another 前.
 - Chinese labels have no uppercase variant. Keep button labels short and avoid splitting short words across lines.
 - The picker displays 中文（繁體） / Chinese (Traditional). Browser tags with Hant or TW/HK/MO select the shared `zh-Hant` catalog. Existing `zh-TW` links and saved choices remain supported. Explicit Hans selects Simplified Chinese, including Hans-TW.
