- Problem: the prune-everything section said the default removes all unused images. Live docker system prune only removes dangling images unless -a is passed. - Fix: say unused containers/networks plus dangling images by default, and that unused tagged images need -a/--all. - Verification: docker 29.1.3 — default warning lists "all dangling images"; docker system prune -a lists "all images without at least one container associated to them". Closed #17488 wanted to change the example to include -a and went stale; this only corrects the default-behavior sentence.

Proposed changes
"Prune everything" should prune all unnecessary components, including unused images. If someone doesn't want to delete unused images, they can omit the "-a" flag. This way, people who want to clean unused components can attain their purpose.
