Crawl4AI v0.8.5 Release Demo - Feature Verification Tests
==========================================================

This demo ACTUALLY RUNS and VERIFIES the new features in v0.8.5.
Each test executes real crawls and validates the feature is working.

New Features Verified:
1. Anti-bot detection - Detects blocked pages and passes normal ones
2. Anti-bot + crawl_stats - Real crawl produces crawl_stats tracking
3. Proxy escalation chain - proxy_config accepts a list with DIRECT
4. Config defaults API - set_defaults affects real crawls
5. Shadow DOM flattening - Crawl a shadow-DOM site with/without flattening
6. Deep crawl cancellation - DFS crawl stops at callback limit
7. Consent popup removal - Crawl with remove_consent_popups enabled
8. Source/sibling selector - Extract from sibling elements via "source" field
9. GFM table compliance - Crawl a page with tables, verify pipe delimiters
10. avoid_ads / avoid_css - Crawl with resource filtering enabled
11. Browser recycling - Crawl multiple pages with memory_saving_mode
12. BM25 content filter dedup - fit_markdown has no duplicate chunks
13. cleaned_html preserves class/id - Verify attributes retained after crawl

Usage:
    python docs/releases_review/demo_v0.8.5.py
