 | Module | Responsibility |
 |---|---|
-| `dialog.js` | `HellionDialog.alert()` and `HellionDialog.confirm()` — custom styled dialogs that replace native browser popups. Loaded first so every other module can use it. |
 | `storage.js` | The **only** place that touches `chrome.storage` / `localStorage`. Everything else goes through `Store.get()` / `Store.set()`. |
 | `state.js` | Global `boards` and `settings` arrays, default values, `uid()`, `escHtml()`, `getFaviconUrl()`. |
+| `i18n.js` | Internationalization module. `STRINGS` object with ~220+ keys (DE/EN), `t(key, vars?)` helper, `applyLanguage()` DOM scanner, `setLanguage()`, `I18n.init()`. |
+| `dialog.js` | `HellionDialog.alert()` and `HellionDialog.confirm()` — custom styled dialogs that replace native browser popups. |
 | `themes.js` | Applies theme CSS variables. 11 themes, each with its own `[data-theme]` block in `main.css`. |
 | `boards.js` | Renders boards and bookmarks. Event delegation on board containers. |
 | `drag.js` | Board and bookmark reordering via Pointer Events API. |
 | `settings.js` | Settings panel UI, toggle handlers, appearance modal, background upload. |
 | `search.js` | Search bar with engine switching (Google, DuckDuckGo, Bing). |
-| `onboarding.js` | Multi-slide first-run flow including the gaming starter board opt-in. |
 | `widgets.js` | Widget manager — creates DOM, handles drag/resize/z-index, provides registry. See [widget-schema.md](widget-schema.md). |
 | `notes.js` | Notes and checklists as widgets. Multi-instance (max 5). Notebook sidebar. Also handles widget toolbar events. |
 | `calculator.js` | Calculator widget. Single-instance. Shunting-yard expression parser — no `eval()`. |
 | `timer.js` | Timer/countdown widget. Single-instance. Presets, Web Audio API alarm, tab-title blink on completion. |
 | `image-ref.js` | Image reference widget. Multi-instance (max 3). Canvas API WebP conversion, sessionStorage for image data — cleared on browser close. |
+| `bookmark-import.js` | Direct browser bookmark import via `chrome.bookmarks.getTree()`. Folder selection modal with duplicate detection. |
 | `data.js` | JSON export/import with validation. Covers boards, notes, calculator history and timer presets. |
+| `onboarding.js` | Multi-slide first-run flow including the gaming starter board opt-in. |
 | `app.js` | Entry point. Calls `init()` on DOMContentLoaded. Clock, global event binding. |

 Scripts are loaded in `newtab.html` in dependency order. A module may only reference modules loaded before it — there is no bundler to handle this automatically.
