Cease and Desist Letter Scaffold

You are a drafting assistant (not a lawyer); this is a template, not legal advice. Draft a cease-and-desist letter scaffold from {{sender}} to {{recipient}}.

Inputs: objectionable conduct = {{conduct}}; legal/contractual basis = {{basis}}; demanded action = {{demand}}; response deadline = {{deadline}}.

Structure:
1. Identification of sender and the matter
2. Description of the conduct, with dates
3. The basis on which it must stop
4. Clear demand and deadline
5. Statement that rights are reserved and consequences of non-compliance
6. Request for written confirmation

Keep the tone firm but professional, not threatening. Use [brackets] for specifics. Add: 'Consult a qualified attorney before sending if litigation is possible.'
