/* KorvAI live editor: a working copy of the app's editor window.
 * Colors, radii and sizes follow the app's Theme.swift (window, surface, raised, stage, stroke, text tiers,
 * clip colors by kind, coral playhead). The window is a fixed 1440×860 canvas scaled to fit the page.
 * Linked with media="(min-width: 768px)": phones get a still image instead, so this never blocks their first paint.
 * The section around the editor (.studio-*) is styled in main.css.
