  * **10. Handle the extraction response and logging the results.**
  *     - Processes the output from the LLM and logs relevant information.
  *
- *
- * Here is what `domExtract` does at a high level:
- *
- * **1. Wait for the DOM to settle and start DOM debugging.**
- *   - Ensures the page is fully loaded and stable before extraction.
- *
- * **2. Process the DOM in chunks.**
- *   - The `processDom` function:
- *     - Divides the page into vertical "chunks" based on viewport height.
- *     - Picks the next chunk that hasn't been processed yet.
- *     - Scrolls to that chunk and extracts candidate elements.
- *     - Returns `outputString` (HTML snippets of candidate elements),
- *       `selectorMap` (the XPaths of the candidate elements),
- *       `chunk` (the current chunk index), and `chunks` (the array of all chunk indices).
- *   - This chunk-based approach ensures that large or lengthy pages can be processed in smaller, manageable sections.
- *
- * **3. Pass the extracted DOM elements (in `outputString`) to the LLM for structured data extraction.**
- *   - Uses the instructions, schema, and previously extracted content as context to
- *     guide the LLM in extracting the structured data.
- *
- * **4. Check if extraction is complete.**
- *    - If the extraction is complete (all chunks have been processed or the LLM determines
- *      that we do not need to continue), return the final result.
- *    - If not, repeat steps 1-4 with the next chunk until extraction is complete or no more chunks remain.
- *
  * @remarks
  * Each step corresponds to specific code segments, as noted in the comments throughout the code.
