+### Removed

 ### Changed
-- Renamed error code prefix `NATI-` to `NATIVEAPPTEMPLATE-` and env var prefix `NATEMPLATE_API_` to `NATIVEAPPTEMPLATE_API_` so the substrate-rename pipeline reaches every product-name occurrence

+- Display `completedAt` as `yyyy/MM/dd HH:mm` regardless of locale
+- Added client-side length caps and truncation for Shop name/description
