 # Changelog
 
+## 0.3.1
+
+### Patch Changes
+
+- 332db0b: Fixed the published output being unloadable under Node's ESM resolver.
+
+  These packages declare `"type": "module"` and only an `exports.import` condition,
+  so Node reads their files as ESM — where relative specifiers need an explicit
+  file extension and a directory never resolves to its `index.js`. `dist` shipped
+  the shortened forms, which bundlers accept but Node rejects with
+  `ERR_MODULE_NOT_FOUND` and `ERR_UNSUPPORTED_DIR_IMPORT`. The build now enables
+  `tsc-alias`'s `resolveFullPaths`, matching what `core` and `devtools` already did.
+
+  `@react-text-game/ui/i18n` additionally imported its English strings from a JSON
+  file, which Node refuses without an `with { type: "json" }` import attribute
+  (`ERR_IMPORT_ATTRIBUTE_MISSING`). Because `core` reaches that entry through a
+  dynamic import inside `Game.init`, and that import is wrapped in a `try/catch`
+  that treats any failure as "the UI package isn't installed", UI strings silently
+  fell back to raw translation keys under Node and SSR. The locale is now a
+  TypeScript module; the exported `uiTranslations` type is unchanged.
+
