Script a product walkthrough people don't skip

Write the in-app walkthrough for new users of my product.

Product: [WHAT IT IS, ONE SENTENCE]
The first thing a new user should achieve: [e.g. send their first invoice, create their first board]
The screen they land on: [DESCRIBE IT BRIEFLY, OR PASTE THE MAIN LABELS ON IT]
Voice: [e.g. friendly and short, no jokes]

Rules:
- Three or four steps, no more. Each step points at one thing on the screen.
- Every step has a title of five words or fewer, one sentence of copy, and a button label.
- Each step should give a reason to continue, not just describe a feature. "Find any invoice in two seconds" beats "This is the search bar".
- The last step ends with the user doing the thing, not reading about it.
- Include the copy for "skip" and for the end state.

Then give me a single HTML file with a mock of the screen made from grey boxes, and the walkthrough playing through the steps on a timer, with a highlight on each target, so I can feel the flow before it's built.
