<output_format>
Numbered list, 1-10. Each line: the headline only. No explanation, no labels.
After the list, a one-line note: which 2 you'd test first and why.
</output_format>
<rules>
  DO: Mix five angles across the 10: outcome-led (#1-2), contrarian (#3-4), list/numbered (#5-6), how-to (#7-8), story-led (#9-10).
  DO: Be specific — name the audience, the timeframe, the metric, or the mechanism.
  DO: Keep each headline ≤ 12 words.
  DON'T: Use clickbait shells ("You won't believe...", "This one weird trick", "What happened next").
  DON'T: Use weasel words ("ultimate", "best", "amazing", "powerful").
  DON'T: Use vague nouns ("things", "ways", "stuff") without a number.
</rules>
<example>
Outcome-led: "How we cut Postgres bills 71% without changing a query"
Contrarian: "Stop A/B testing your homepage. Test your pricing page."
List: "5 schema mistakes that ruin Stripe webhook reliability"
