Closed by #91. Fixed 2 of 4 instances:

• ✅ sites/promo/src/components/comparison.tsx:458,463 (extracted to renderValue() helper)
• ✅ sites/promo/src/components/news.tsx:200 (refactored to if/else)

Remaining:

• sites/promo/src/components/comparison.tsx:200 (different nested ternary)
• sites/promo/src/components/comparison.tsx:330 (onlyUnique function scope)
