年長男子在溫馨客廳彈奏老式直立鋼琴，陽光透過蕾絲窗簾，沙發上有隻貓在睡覺

提示詞

An elderly man playing an old upright piano in a cozy living room, soft afternoon light through lace curtains, sheet music on the stand, a cat sleeping on the sofa nearby, ultra-detailed textures – piano keys, wrinkled hands, lace curtain movement, realistic warm nostalgic style, cozy color palette of browns, creams and soft golds, 16k resolution. Animation (10 seconds): STRONG START – At 0–2 seconds sudden close-up on fingers pressing keys with first chord ringing out. At 3 seconds the camera transitions into smooth side tracking around the piano. Final 4 seconds: the tracking rises gently upward revealing the full room and cat, ending with powerful hold on his peaceful smile as he finishes the melody. Soundtrack: Warm piano notes at start, layered with soft cat purring and curtain rustle, gentle nostalgic melody rising to emotional climax.
