 - Localizations: add Spanish and Catalan language packs and fill missing localization keys (#1041). Thanks @seifreed!
 
 ### Fixed
+- Localization: translate provider-detail labels and empty states when Simplified Chinese is selected (#1051). Thanks @wang93wei!
 - Antigravity: discover OAuth credentials from the bundled extension language server in newer IDE builds so Add Account works again (#1076). Thanks @xARSENICx!
 - Menu bar: wait for display changes to settle before recovering status items and retry if macOS still leaves the icon detached (#1074). Thanks @yipjunkai!
 - Menu: keep lower action rows stable when Refresh is highlighted or pressed (#1071). Thanks @MadanChaollaPark!
