スタイルプロンプト（Claude Motion または Opus 5.5）
Make an 8-second 16:9 before-and-after comparison for [who will watch, e.g. customers], playing [where, e.g. the redesign announcement]. Use only the two screenshots and the title I give. Dark background.
The title fades in above a large rounded frame showing the before screenshot in grayscale, labeled "BEFORE". A white vertical divider with a round handle sweeps from right to left, revealing the after screenshot in full color with an orange "AFTER" tag. End frame: the divider swings back to about three quarters and settles in the middle.
Title: [e.g. "The redesign"]
Attach: [a before screenshot and an after screenshot, same size]
