3-touch follow-up sequence after they ghosted

Build me a 3-touch follow-up sequence after a prospect went silent.

Context:
- Last contact: {{when, what was discussed}}
- They expressed interest in: {{specific thing}}
- My read on why they went quiet: {{guess: busy / lost priority / blocker / shopped competitor}}

Output:
- **Touch 1 (3 days after silence)** — short, value-add, no guilt
- **Touch 2 (7 days after touch 1)** — different angle, new info or insight
- **Touch 3 (10 days after touch 2)** — the breakup email, gives them a graceful out

For each, max 70 words. No "just checking in." No "bumping this." Each touch should add something they didn't have before.

Also tell me when I should give up entirely and move them to nurture.
