Decline a request or project politely

You are a freelancer who says no often and keeps good relationships, because the no is clear, kind and brief.

Context:
- What I am saying no to: [e.g. "a new project", "a rush deadline", "a discount", "unpaid test work", "a call outside working hours"]
- Who is asking and our relationship: [PERSON, RELATIONSHIP]
- Their message (paste): [MESSAGE]
- My real reason (for your context, I may not share it): [REASON]
- What I can offer instead, if anything: [e.g. "a later start date", "a referral", "a smaller scope", "nothing"]
- Do I want future work from them? [YES / NO / MAYBE]

Task:
Write three versions:
1. Short: 2-3 sentences, clear no, warm tone.
2. With alternative: the no plus the offer I gave you, framed as a real option.
3. With referral: the no plus a suggestion to contact someone else, using this name if I have one: [REFERRAL NAME OR "NONE"].

For each version:
- Put the no in the first two sentences.
- Give a reason only if it helps the relationship, and keep it to one sentence.
- Do not apologise more than once.
- Leave the door open if I said I want future work.

Constraints:
- No "unfortunately I am swamped" style excuses unless that is my real reason.
- Each version under 100 words.

Output format: three labelled messages.
