Use InterfaceSkelete to start building a WordPress-like editor

I want this only to later on show the sidebars with the inserter and
inspector, but for now, since i do not understand yet how i am
supposed to use ComplementaryArea, i add the interface with the
breadcrumb at the bottom.

The FullscreenMode block is to “cancel out” the 160px margin on the
left, and 32px on the top, that @wordpress/interface’s style add by
default.
