@viewport.min-zoom

The min-zoom CSS descriptor sets the minimum zoom factor of a document defined via @viewport. The browser will not zoom out any further than this, whether automatically or at the user's request.

A zoom factor of 1.0 or 100% corresponds to no zooming. Larger values zoom in. Smaller values zoom out.
