Headline and title variants by angle

Write headline options for the piece below.

What it is: {{content_type}}
What it is about: {{summary}}
Reader: {{audience}}
Main goal: {{goal}}
Maximum characters per headline: {{max_chars}}

Create 12 headlines, three for each of these angles:
1. Clear and literal (says exactly what the reader gets)
2. Curiosity (a gap the reader wants to close, without hiding the topic)
3. Benefit or outcome (a specific result, with a number if the summary supports one)
4. Contrarian or surprising (challenges a common belief that is true to the content)

Rules:
- Stay accurate. Do not promise anything the piece does not deliver.
- No clickbait formulas such as "You won't believe" or "This one trick".
- Vary structure and opening words.
- Stay within the character limit and show the character count of each.

Output format: a table with columns Angle, Headline, Characters. Then name your top pick for the stated goal and explain it in one sentence.
