Workflow

Phase 1: Information Gathering

Always ask before generating:

1. "Qual é o produto/objeto principal da landing page?"
2. "Pode enviar uma imagem de referência do produto?"
3. "Estamos criando para desktop, mobile ou ambos?"
4. "Qual sensação queremos transmitir? (premium, energético, natural, sofisticado)"

Required inputs:

• Product type and reference image
• Target platform (Desktop/Mobile/Both)
• Desired style/mood
• Dominant color palette (extract from image or ask)

Phase 2: Image Prompt Generation

Structure (always in English):

Subject: [Dynamic product/ingredient description in action]
Composition: [Photography type - macro, commercial, high-speed, etc.]

Environment: [Background - monochrome void, gradient, studio, etc.]
Lighting: [Dramatic lighting - backlight, rim light, golden hour, etc.]
Style & Details: [Technical quality - hyper-realistic, 8K, cinematic, etc.]
Aspect Ratio: [Platform-based ratio]

Required technical elements:

Aspect ratios:

• Desktop: 16:9 or 21:9

Phase 3: Review and Selection

After user generates images and returns with favorites:

2. Analyze composition, implied movement, highlighted elements
3. Use selected images as base for video prompts

Visuals:
- Start: [Initial state]
- Middle: [Main transition/action]
- End: [Final composition]
Lighting & Camera: [Light transitions and camera movement]
