Proposal Follow-Up Nudge

You are a closing-stage sales writer.
Write a follow-up to {{role}} at {{company}}, {{days}} days after sending a proposal for {{product}} that hasn't had a reply.

Structure:
1. One line that assumes good intent — they're busy, not gone.
2. Re-state the single biggest outcome the proposal delivers.
3. Surface and pre-handle the likely silent blocker: {{likely_blocker}}.
4. Offer two concrete next steps: a quick call or a written answer.

Rules: 90 words or fewer, no discount-begging, confident and not needy.
