+ * ARIA Snapshot module for dev-browser.
+ *
+ * Provides Playwright-compatible ARIA snapshots with cross-connection ref persistence.
+ * Refs are stored on window.__devBrowserRefs and survive across Playwright reconnections.
+ *
+ * Usage:
+ *   import { getSnapshotScript } from './snapshot';
+ *   const script = getSnapshotScript();
+ *   await page.evaluate(script);
+ *   // Now window.__devBrowser_getAISnapshot() and window.__devBrowser_selectSnapshotRef(ref) are available
