/**
 * The furniture pane once declared `initial={{ opacity: 0 }}` / `animate={{
 * opacity: 1 }}` through motion's minimal `motion/react-m` entry. That entry
 * renders the element but never runs the animation, so the inline style stayed
 * at opacity: 0: every row was in the DOM, measurable, and its image loaded,
 * yet the whole list was invisible.
 *
 * studio.spec.ts could not catch it because playwright.ui.config.ts sets
 * `reducedMotion: "reduce"`, and under reduced motion the animation is skipped
 * and the element lands straight on its final value. This file opts out of that
 * so a future animation swap cannot quietly hide the list again.
