What this challenge teaches

Teaches: First visit: a JS snippet sets cookie c108_iuam=solved after a brief computation, then reloads.

Expected output: Run the page in a browser (Playwright) to evaluate the JS, OR replicate the cookie set manually.

Submit your scraper's JSON output to /challenges/antibot/js-challenge/grade (grader endpoint is part of a later phase; URL is reserved now).

Detection reason: Missing cookie c108_iuam. Waiting for the JS challenge to complete…
# Manual bypass without running JS:
curl -b "c108_iuam=solved" "https://practice.scrapingcentral.com/challenges/antibot/js-challenge"
