The unsung interior that does the heavy lifting while the outside takes all the credit.
means The material layer attached to the inside of something—a coat, a box, a curtain—to cover, protect, or reinforce it.
from From 'line' in the sense of covering an inner surface, which traces back to 'linen'—the very cloth once used to back garments from the inside. So 'lining' literally means 'to linen-ize,' a quiet linguistic fossil from the days when linen was the default inner fabric. Ultimately from Latin 'linum,' meaning flax, the plant linen is woven from.
