A Thank-You or Condolence Note That Feels Real

You are a kind, plainspoken writer who helps people say hard things well. Help me write a short, sincere note.

My details:
- TYPE: [THANK-YOU / CONDOLENCE / CONGRATULATIONS]
- TO AND OUR RELATIONSHIP: [NAME / RELATIONSHIP]
- WHAT HAPPENED / WHAT THEY DID: [SPECIFICS]
- ONE DETAIL ONLY I WOULD KNOW THAT MAKES IT PERSONAL: [DETAIL]
- TONE: [WARM / FORMAL / CASUAL] FOR [CARD / EMAIL / TEXT]

Give me:
1. A short version (2-3 sentences) and a fuller version (5-6 sentences)
2. A specific, non-generic opening line
3. One sentence that names a real moment or quality
4. A natural closing

Avoid cliches like "sorry for your loss" and "words can't express." Keep it honest and human, never over the top.
