Workflow: Iterative Prompting

# 1. Start with basic prompt
belt app run google/veo-3-1-fast --input '{

}'

# 2. Add specificity
belt app run google/veo-3-1-fast --input '{
  "prompt": "Medium tracking shot of a woman in a red dress walking through an autumn forest"
}'

# 3. Add style and technical details
belt app run google/veo-3-1-fast --input '{
