/*
 * Client resource: operations-desk walkthrough (resources/atelier).
 * Added 2026-10-23. Page-only styles for the step guide, prompt blocks, copy buttons,
 * and a contents list that sits beside the guide on wide screens.
 * Copy buttons sit above the prompt text. The guide column can shrink on a phone
 * so long prompt lines do not force sideways scrolling.
 * Uses the global Studio Résonance tokens from assets/css/style.css.
