Dark moody palette: deep midnight indigo and dark violet background with shimmering opal, pearl-white, lilac and pale-gold illusory glow, mirage-like light flares. Intricate baroque border. At the bottom, luxurious gold-foil serif title in Russian Cyrillic reading "ДВОР ПРИЗРАЧНЫХ СЕРДЕЦ". Atmospheric, haunting, dreamlike, illusory, premium fantasy novel cover, symmetrical composition, matte dark background, sharp focus, correct Russian Cyrillic spelling.
