Glossary (EN–ZH)
The single source of truth for terminology across the site. Mistranslated terms tell a specialist reader immediately that a product is amateur.
Every translation on this site follows this table. Documentation, interface, emails and legal text all use these renderings — improvisation is not allowed. If a rendering is wrong, fix it here and then fix it everywhere — not in one place only.
