Create a 30-45 second English product update video for the fictional Alder Desk app. Use product-flow-before.svg and product-flow-after.svg as the only interface references. Fact packet: Archiving now shows a confirmation step. No project is removed until Confirm archive is clicked. Do not claim undo or recovery. Audience: existing users. Show the changed workflow with legible interface labels, restrained motion, English captions, and no avatar. CTA: Try Confirm archive in Projects. Do not invent screens, pricing, integrations, availability dates or performance claims. Produce a 16:9 preview. Describe the actual download options separately.
