Draft a GDD outline with content for each section:
1. Vision and pillars (3 design pillars that guide every decision)
2. Player fantasy — what does the player feel they ARE?
3. Core loop — the 30-second loop the player will do thousands of times
4. Meta loop — what unlocks, progresses, and pulls them back tomorrow
5. World and tone — visual + audio direction
6. Story / narrative hook
7. Key mechanics — top 3 only, with depth and constraints
8. Progression and economy
9. UX principles
10. MVP scope — what's the smallest playable version that proves the fun?
11. Risks and unknowns
12. Reference moodboard (describe in words)

End with the single playtest question that, if answered "yes," would prove the game works.
