CI fixtures without live Leonardo Phoenix calls
Branch previews that call Leonardo Phoenix turn every open PR into a mini art bill. Verification pipelines should not inherit creative habits from demos.
Where image API costs go off the rails
Preview environments are silent budget leaks

Designers and agents disagree on cost
Humans would reuse a mock; agents re-prompt Leonardo Phoenix from scratch each time.
Budget planning is guesswork
Open-ended Leonardo Phoenix usage is hard to forecast. Flat stock is not.
Scenario: CI & fixtures with Leonardo Phoenix
Load tests that include image generation will measure the wrong bottleneck and the wrong bill. Keep Phoenix out of CI; use Epochal fixtures.
