Return 5 distinct subject lines, each tagged with the hook style:
- 1. Curiosity — open loop, makes them need to know
- 2. Direct benefit — what they get, in plain English
- 3. Question — pulls them in by addressing them
- 4. Specific number / data — credibility through specificity
- 5. Personal / contrarian — surprising or vulnerable

For each: subject line + 1-line note on why it works. Below the 5, add a 'Recommended A/B pair' line picking the 2 most likely to win. AU spelling. No emojis unless they fit the brand. No clickbait ('You won't believe...').
