무도회 배경

An elegant grand ballroom interior prepared as a reusable image-generation background, tall arched windows, polished herringbone parquet floor, crystal chandeliers, warm candlelight mixed with cool moonlight, cream and muted burgundy palette, symmetrical wide composition with generous empty center space for characters, realistic architectural detail, 24mm wide-angle lens, subtle atmospheric depth, no people, no logos, no watermark.
