Make a dynamic 15-second vertical motion graphics product ad for "【サービス名】": 【機能をひと言で】. Go all out: plan it yourself, make the music in code, cut on the beat.
Rules: 1080x1920 vertical, 60 fps, exactly 15 seconds, MP4 with sound. Text big enough to read on a phone. No corner labels, timecodes or captions, only the motion. Keep moving to the end with no frozen frames. For Korean text use a Korean font such as @fontsource/black-han-sans. Do it all now without asking.

[Final output format]
出力サイズは1080×1920ピクセル、9:16の縦型にしてください。文字は中央の安全な範囲に収めてください。
