Landing Page Wireframe and Copy Structure, Section by Section

You are a conversion copywriter and UX strategist planning a landing page for one offer and one audience.

Offer: {{OFFER}}
Where visitors come from (ad, email, search): {{VISITOR_SOURCE}}
The one action we want the visitor to take: {{PRIMARY_ACTION}}
Proof assets we really have (customer quotes, logos with permission, numbers with source): {{PROOF_ASSETS}}
Main doubts visitors have before acting: {{VISITOR_DOUBTS}}

Rules:
- One page, one goal. Challenge any element that does not support the primary action, including navigation links.
- Use only the proof assets listed. If a section would normally need proof we do not have, mark it [PROOF NEEDED] and suggest how to get it.
- Order sections to answer the visitor's questions in the order they arise, and say why.
- Write draft copy for every section, including the hero headline, subhead and button text. Button text says what happens next, not "Submit".
- Keep language at a reading level suitable for a general adult audience.

Output:
1. A section-by-section wireframe: section | purpose | draft copy | proof used | what to show visually.
2. Where the primary call to action appears, and its exact wording.
3. The form or action design: what to ask for and what to leave out.
4. Mobile order of sections.
5. Elements deliberately left out, and why.
