The Seed & Iteration Strategy

Design an iteration strategy for this shot.

Shot: [DESCRIBE]
Platform: [NAME]
Credit budget: [DESCRIBE]
How close I am currently: [DESCRIBE]

Produce:
1. What to change first — the single variable most likely to fix
   the problem
2. What to change one at a time versus what to change together
3. When to keep the seed fixed and vary the prompt, and when to do
   the reverse
4. How many attempts before concluding the shot is not achievable
   as specified
5. The fallback: what simpler version of this shot to try instead
6. What to record about each attempt so I can reproduce a good one

The most common iteration mistake: changing four things at once and
learning nothing from the result. Structure this so each attempt
teaches me something.
