/*
 * SPA-safe Settings panels
 * ------------------------
 * The original PHP page used a DOMContentLoaded settings.js file to add `.is-active`.
 * In the React SPA, client-side navigation does not fire DOMContentLoaded again.
 * Therefore the safe default must be visible content, with `[hidden]` used only
 * when React or the old initialiser has explicitly hidden inactive panels.
