// @vitest-environment jsdom
//
// Locks the stacking that makes an admin config row usable on a phone. The
// control column cannot shrink, so beside a wide control it left the label and its hint a sliver of
// the ~250 px a phone leaves next to the navigation rail. The sibling fix — a long-labelled choice
// becoming a dropdown — is covered in ConfigPanel.choice.dom.test.tsx, but that one does nothing for
// a text, number or secret key, whose `w-52` input is the wide control: this is their only fix.
//
// jsdom does no layout, so what is asserted is the class contract those rules rest on, the same
// trade SearchBar.dom.test.tsx already makes for the narrow-header rules.
