/* Premium hover-OFF: when you move away from a canvas the revealed painting should
   fade out SLOWLY, not blink. Forced with !important so it also applies when the OS
   has reduced-motion on (app.css drops the reveal to 0.3s linear there, which reads
   as an instant blink) — a gentle opacity fade is reduced-motion-safe. The base
   .art-g rule governs the transition toward the hidden state (the fade-OUT); the
   .is-on rule governs the reveal-IN (kept a touch quicker so it still feels snappy). */
