I need headline options for the following content piece. Give me 10 headlines, and I want VARIETY — don't give me 10 versions of the same angle.

**Content topic:** [e.g., "Why async standups outperform synchronous ones for remote teams"]
**Format:** [e.g., "Blog post, ~1500 words, data-backed argument"]
**Target audience:** [e.g., "Engineering managers at remote-first companies, 30-45, pragmatic, skeptical of productivity fads"]
**Tone:** [e.g., "Direct, evidence-based, slightly contrarian"]

For each headline, use a DIFFERENT angle:
1. A number/data hook
2. A "how to" practical hook
3. A counterintuitive/contrarian hook
4. A question hook
5. A "mistake" or "stop doing X" hook
6. A curiosity gap / incomplete information hook
7. A comparison hook ("X vs Y")
8. A specificity hook (ultra-specific detail)
9. A stakes/consequence hook ("what happens when...")
10. A social proof / trend hook

After all 10, mark your top 3 picks and explain why each would perform well for this audience. Bold the words in each headline that carry the most psychological weight.
