How the Comet 4 fits into the Comet story

Why it branches from the family
The Comet 4 is treated as the representative branch because it captures the mature long-range branch that returned the line to transatlantic passenger service.
Variant pages stay intentionally narrower than the family page so differences in cabin, engines, mission, and market role remain clear without duplicating the full program history.
