/**
 * Citation extraction for NotebookLM answers (issue #20).
 *
 * NotebookLM renders citation markers like `[1]`, `[2]` inside the answer and
 * — in a separate panel — the cited passage from the source document. v1
 * required the LLM to spell those out manually, which wasted tokens and was
 * unreliable. v2 reads the citations directly from the DOM after the answer
 * settles.
 *
 * Approach:
 *   1. Read all `button.citation-marker` inside the *latest* answer container
 *      (so previous answers in the same session don't bleed in).
 *   2. For each marker, click it to open the source panel, read the
 *      highlighted passage out of `.paragraph .highlighted`, then press
 *      Escape so the chat input remains usable for follow-up questions.
 *   3. Return structured `Citation[]` and a formatted variant of the answer
 *      according to the requested `SourceFormat`.
 *
 * All NotebookLM-facing CSS lives in the central selector registry, so a
 * single UI change cannot break both this module and chat extraction.
