为一个虚构 App 做的「重力开关」宣传片

Make an 18-second 16:9 product launch film for [who will watch, e.g. product managers], playing [where, e.g. our homepage hero and X]. Use only the name, lines and screenshot I give below; don't change a word. Near-black background with a warm orange glow.

Scene 1 (0–3.4s): a two-line hook rises from masks, line one off-white, line two orange, slowly pushing in. An orange wipe cuts to Scene 2: the product name and tagline on the left while a browser window with the screenshot rises from below with a 3D tilt and settles. Scene 3: three features one at a time, each with a huge orange numeral (01, 02, 03), a bold title and a gray description, with a segmented progress bar at the bottom. End frame: the logo mark spins in, then the name, an orange call-to-action pill and the URL.

Hook: [two lines] (e.g. "Your roadmap" / "finally in motion")
Product and tagline: [e.g. Northwind, one line]
Features: [three titles with one-line descriptions]
Call to action and URL: [e.g. "Start free", northwind.dev]
Attach: [a screenshot of your product]
