Review checklist

• Technically accurate -- no confident-sounding but wrong explanations
• Jargon defined before first use
• Code (if present) is correct and matches what the text claims
• Recap of the previous day reads naturally (if present)
• "Coming up next" teaser is accurate to tomorrow's actual topic
• Matches the series' teaching voice (patient, not senior-engineer-only)
