+I will optimize the loading process by implementing a **Multi-Threaded Worker Loader**. This involves creating a pool of Web Workers to fetch assets (JavaScript, Audio, Images, Views) in parallel, offloading the network initiation and handling from the main thread.
+
+### Plan:
+1.  **Create `public/src/js/loader-worker.js`**:
+    *   This worker will handle `fetch` requests for different resource types (`text`, `blob`, `arraybuffer`).
+    *   It will transfer the data back to the main thread (using zero-copy transfer for `ArrayBuffer`).
+
+2.  **Modify `public/src/js/loader.js`**:
+    *   **Initialize Worker Pool**: Create a pool of workers (defaulting to 4) in the `Loader` class.
+    *   **Implement `workerFetch(url, type)`**: A method to distribute fetch tasks to the worker pool.
+    *   **Override `ajax(url, ...)`**: Intercept requests for static assets (`src/`, `assets/`, etc.) and route them through `workerFetch`. Keep API calls (`api/`) on the main thread to ensure session stability.
+    *   **Update `loadScript(url)`**: Change it to fetch the script content via `workerFetch` and inject it using a `<script>` tag with inline content. This ensures JS files are also loaded via the "multi-process" mechanism.
+    *   **Update `loadSound` and `RemoteFile` logic**: Since `RemoteFile` uses `loader.ajax`, routing `ajax` to workers will automatically parallelize audio loading.
+
+### Technical Details:
+*   **Concurrency**: 4 Workers will be used to maximize throughput without overloading the browser's connection limit per domain.
+*   **Resource Types**:
+    *   **JS/Views**: Fetched as `text`.
+    *   **Images**: Fetched as `blob` -> `URL.createObjectURL`.
+    *   **Audio**: Fetched as `arraybuffer` -> `AudioContext.decodeAudioData`.

+		// Make it a small button accompanying EACH difficulty?
+		//
+		// In my plan: "In songselect.js ... add 'Leaderboard' button to diffOptions".
+		// If I follow this, clicking it needs to probably show the leaderboard for *some* difficulty,
+		// or the UI should let you pick.
+		// `LeaderboardUI` supports `show(songId, difficulty)`.
+		// Let's make it show "Oni" by default if available, or the highest available.
+		// And add tabs in LeaderboardUI to switch difficulty?
+		// Or, simpler: Just show Oni for now, or last played.
+		//
+		// Actually, looking at `LeaderboardUI` code I wrote: it takes `difficulty` in `show`.
+		// I did NOT implement tabs in `LeaderboardUI`.
+		//
+		// Alternative idea:
+		// When user hovers/selects a difficulty (e.g. Oni), maybe press a key to see leaderboard?
+		// But the requirement was "Add a Leaderboard option".
+		//
+		// Let's check how "Download" works. It downloads the current song.
+		// "Song Options" opens a menu.
+		//
+		// If I make "Leaderboard" a menu item, I should probably show the leaderboard for the *currently selected song*
+		// but which difficulty?
+		// Let's default to Oni. 
+		// Better: The leaderboard UI should have difficulty tabs.
+		// Since I can't easily redesign `LeaderboardUI` in this tool call (it's already written),
