Claude prompt: 14-second product film for an invoicing app (16:9)

Build a 14-second motion design product film in 16:9 (1920x1080, 30 fps) for my app , which . Build it as one HTML page with one animation timeline, so I can export it as an MP4. Look: light grey-green background with a soft grid, white cards with thin borders, one brand colour , one clean sans-serif font. The text builds word by word: "" / " , , and for you." / "." Scene 1: the hook question, big and centred. Scenes 2 to 4: one card shows each step. The card from one step becomes the object of the next step. Scene 5: the result with a small "done" stamp. Scene 6: logo, name and "". Rules: the camera never stands still. Every move is eased. Key words are in the brand colour, the rest stays dark.
