New checks (from EUIPO reference case):
- Check 9: Third-party DSE link — detects when consent dialog links to
external domain's privacy policy instead of own DSE (Art. 13 DSGVO)
- Check 10: Dark-pattern language — detects "muessen/erforderlich" for
non-essential cookies suggesting false technical necessity (EDPB Rn. 70)
- Check 11: Non-modal dismiss = consent — detects when clicking outside
dialog closes it (possibly treating as consent, Planet49 violation)
Refactor: extracted _check_banner_text (375 LOC) from consent_scanner.py
into services/banner_text_checker.py to keep both files under 500 LOC.

1. Impressum link accessible from banner (§5 TMG, LG Rostock)
2. DSE link in banner (Art. 13 DSGVO, informierte Einwilligung)
3. Wrong wording: "Zustimmung zur DSE" — DSE is Art. 13 obligation,
not consent. Correct: "zur Kenntnis genommen"
4. Reject button visible (§25 TDDDG, no hidden reject)
5. Pre-ticked checkboxes detected (EuGH C-673/17 Planet49)
6. Dark Pattern: button size comparison — accept vs reject area
ratio >2.5x or font size ratio >1.5x = dark pattern
7. Cookie Wall detection (Phase B — site blocked after reject)
8. Re-access to settings (Art. 7(3) — revocation as easy as consent)
All checks run via Playwright on the actual rendered banner.

Tests each consent category in isolation:
- Phase D: Only "Statistics" enabled → checks if only analytics loads
- Phase E: Only "Marketing" enabled → checks if only ads load
- Phase F: Only "Functional" enabled → checks no tracking loads
CMP-specific category selectors for Cookiebot, OneTrust, Usercentrics,
Didomi. Generic fallback via toggle/checkbox keyword detection.
SERVICE_CATEGORY_MAP maps 35+ services to expected categories.
Violations: "Facebook Pixel loads with only Statistics enabled" = miscategorization.
Frontend: category test results shown below Phase A-C with
per-category violation cards.

New independent service (port 8094) with headless Chromium:
- Phase A: What loads BEFORE any consent interaction
- Phase B: What loads AFTER rejecting consent (CRITICAL if tracking persists)
- Phase C: What loads AFTER accepting (check against cookie policy)
- 10 CMP-specific selectors (Didomi, OneTrust, Cookiebot, Usercentrics, etc.)
- Generic fallback via button text matching
- 18 tracking service patterns for script classification
