Facebook Group Scrape & Export

I need the entire history of a specific Facebook Group captured—every post along with all associated comments. I’m interested in both the text and any embedded media (photos, videos, GIFs). When you deliver, I’d like the result to look as close to the native Facebook view as possible, so a self-contained HTML archive or similarly styled output that preserves threading, author names, timestamps, and inline media would be ideal.

Your script or tool must avoid triggering Facebook rate limits and respect login or session requirements; please let me know what credentials or cookies you will need me to supply. Once the crawl is complete, I expect a single downloadable package that I can open locally and browse through just like I would inside the browser, with working links to the images and videos placed in clearly named folders.

Please outline:
• your scraping approach (Python + Selenium, Go, node-puppeteer, etc.),
• how you’ll handle media downloads and folder structure,
• estimated turnaround time.

I’ll review a short sample export before we proceed with the full run to confirm the layout meets my “looks the same in browser” requirement.
