 The script creates `data/db` and `data/files`, refreshes the generated browser libraries, builds the project, and starts it with Cargo. If Cargo is unavailable, it runs `docker compose up --build` instead; the Docker build downloads the libraries in a separate stage.

+## Interface languages
+
+Frontend translations live in the top-level `lang/` directory and are embedded into the Rust binary during the build. There is no separate language manifest: every `*.json` file is discovered automatically and its `meta` block is used to populate the language selector in the profile.
+
+```json
+{
+  "meta": {
+    "code": "pl",
+    "name": "Polish",
+    "native_name": "Polski",
+    "locale": "pl-PL"
+  },
+  "translations": {
+    "common.save": "Zapisz"
+  }
+}
+```
+
+`lang/en.json` is the required fallback and source language. Every language file must have the same translation keys as `en.json`; invalid metadata, non-string values, duplicate codes, or mismatched keys are rejected when the embedded language catalog is initialized. To add a language, copy `lang/en.json`, translate the values, and set `meta.code`, `meta.name`, `meta.native_name`, and `meta.locale`. The filename must match `meta.code` (for example `de.json` and `"code": "de"`).
+
+The selected interface language is stored in the browser and can be changed from the profile without reloading the page. API responses remain in their original English form; the browser client translates known messages only when presenting them in the UI.
