The prompt that makes a product video without a video editor

You are my motion designer. Make a product demo video for [PRODUCT NAME], a [ONE LINE: what it is and who it's for].

You have access to this repo. Before designing anything, read it so the video shows the real product:
- the actual screens, in the order a real user meets them
- the exact words on those screens. Do not invent copy
- the brand: colours, fonts, logo, spacing. Use them everywhere

Imagine you are a [TYPE OF USER, e.g. new paid user]. Walk through the product as they would:
1. [FIRST THING THEY DO, e.g. sign up and see the welcome screen]
2. [FEATURE 2]
3. [FEATURE 3]
4. [FEATURE 4]
5. [FEATURE 5]
6. [THE RESULT OR PAYOFF THEY GET]

How to build it:
- Use Remotion (React), so every frame is code and it renders to MP4 with no extra installs.
- Before writing any animation, decide how many seconds each feature gets and show me the plan. Keep it fast. Nothing slow or boring.
- Rebuild the product's interface inside a device frame. Show real interaction: typing, taps with a visible touch, messages arriving, notifications sliding in.
- Build the layout so one timeline renders both a wide and a vertical version.
- Move the camera. Push in on what matters, pull back between steps.
- Put a short caption with each step: a number, a label, a headline, one supporting line. Large enough to read on a phone.
- Open on the logo and tagline. Close on the logo, what the product does in three words, and a call to action: [YOUR CTA AND LINK].
- Make the very first frame a finished cover image, because most apps use it as the thumbnail.

Sound:
- Write an original soundtrack in code so there is nothing to license. Pick a tempo and start every section on a bar, so cuts land on the beat.
- Add interface sounds: taps, typing, send, incoming message, notification. Time them from the same file that times the visuals, so they can never drift apart.

Quality:
- Render review frames of every scene and check them yourself before the final export. Fix anything cropped, overlapping or too small to read.
- Export 1920x1080 for desktop and 1080x1920 for Instagram and X, at high quality so it survives compression.
- Use example data for any numbers and tell me which ones are examples. Never show private data: no keys, no real users, no real accounts.

Use your best motion design judgement throughout. I'm attaching [A REFERENCE VIDEO / MY LOGO] to show the level of polish I want. Do not copy it.
