/**
 * Page utilities for extracting prior answers from NotebookLM.
 *
 * Streaming-stability detection has moved to `notebooklm/chat.ts`
 * (`waitForStableAnswer`, issue #43). The old `waitForLatestAnswer` here
 * polled `div.thinking-message`, which Google removed — calls timed out
 * even when the answer was already on screen. That logic is gone.
 *
 * What remains:
 *   - `snapshotAllResponses(page)` — used by `BrowserSession.ask()` as a
 *     fallback when the v2 chat snapshot returns nothing. It captures the
 *     visible answer texts *before* a new question is submitted so the
 *     stability detector can ignore them on the next turn.
