スタイルプロンプト（Claude Motion または Opus 5.5）
Make a 7-second 16:9 launch countdown for [who will watch, e.g. our followers], playing [where, e.g. the livestream and X the hour before launch]. Use only the date and line below. Pure black background.
Small uppercase "LAUNCHING IN" sits at the top. A thin white ring drains clockwise around each number as huge white numerals 3, 2, 1 slam in from a blurred, oversized state and shrink away. After 1, the ring blows outward and an off-white flash fills the frame. End frame: the launch line settles in with tightening letter spacing above the date and time in gray.
Launch line: [e.g. "Live now"]
Date and time: [e.g. "Oct 21 · 10am PT"]
