Explain a CO₂ reading
Explains a bedroom CO₂ reading against the precautionary 800 ppm average-while-asleep goal: band, distance from the goal, whether the measurement is comparable, signs of a monitor reading low, and free fixes with trade-offs. The goal is not a health limit. Door-open nights appear only as one-night tests, not fixes.
