What is the essential role of a planet's atmosphere in modifying conditions relative to the calculated HZ?

Answer

Atmospheric composition and density act as critical buffers against temperature swings.

Atmospheric features, especially greenhouse gases, trap heat, warming the surface by a measurable amount and effectively pushing the planet's habitable conditions slightly inward from the theoretical HZ boundary.
