2 * Aesthetic Computer - Webview Preload Script
3 *
4 * This preload runs inside the webview (the AC content) and provides
5 * a bridge to communicate with the parent Electron renderer (flip-view.html).
6 *
7 * Uses ipcRenderer.sendToHost() which is specifically designed for webview → parent communication.
