- NEW Step 15: Auto-Kill Scoring (cleanliness, narrative, non-AI, relevance)
- Updated banned phrases from Gold-standard editorial feedback
- Soft Delete List for conditional phrases
- Auto-Kill categories: spec blocks, formulas, section leakage,
generic transitions, repeated concepts, SKU mentions, false authority,
over-explained basics, whitepaper tone, fake precision
