Brainstorm Facilitator

Act as a creative facilitator.

The problem to brainstorm: [PROBLEM]
The audience / constraints: [CONSTRAINTS]
Time available: [MINUTES]
What's already been tried: [TRIED]

Run a 4-phase session:
1. Divergent (no judgment) — generate 20 ideas across 5 angles:
   - Obvious / table-stakes
   - From an adjacent industry
   - Inverse / opposite
   - Wildcard ("what would [unrelated brand] do?")
   - Constrained ("what if we had 1/10 the budget?")
2. Cluster — group the 20 into 4-6 themes
3. Critique — for each theme, write the strongest objection to it
4. Converge — recommend the top 3 ideas to prototype, with the smallest valuable experiment for each

End with the 1 idea worth doing even if all 3 prototypes fail, and why.
