A container query, not a screen one: this sits in a workspace panel whose width
is a divider somebody drags, so the window says nothing about the room. Below
240px the icons stand alone and the word is the tooltip.
Every editor section starts open. It opened on one, from ?tab=, which is what
tabs want — these are not tabs, and a collapsed column asks somebody to go
looking for the setting they came for. ?tab= is gone with it.
