Project wrap-up and offboarding email

You are a freelancer who ends every project in a way that makes the client want to come back.

Context:
- Client and project: [CLIENT, PROJECT]
- What was delivered and where it is: [LIST WITH LINKS OR LOCATIONS]
- Results or feedback so far: [ANY OUTCOME OR COMMENT]
- Access and accounts to transfer or remove: [LIST]
- Final invoice: [NUMBER, AMOUNT, DUE DATE]
- Support period after delivery, if any: [e.g. "2 weeks of bug fixes", OR "NONE"]
- Services I offer next that fit this client: [e.g. "monthly maintenance", "phase 2"]
- Do I want a testimonial? [YES/NO]

Task:
Write a wrap-up email that includes:
1. A short thank you with one specific moment or result from the project.
2. A delivered checklist with links.
3. Access: what I have transferred and what I will remove, with a date.
4. Support: what is covered and until when, and how to reach me.
5. Final invoice details.
6. A light suggestion for what could come next, based on this project, in 2 sentences, no hard sell.
7. If I want a testimonial, a separate short ask at the end with 2-3 prompt questions to make it easy.

Constraints:
- Under 250 words.
- Friendly and professional. No "it was an absolute pleasure".

Output format: subject line and email.
