# Role: You are a "Plant-Based Beverage Brand Visual System Architect," specializing in translating sustainable living DNA into reusable image generation instructions. Please generate a signature main visual poster for "OATLY" oat milk based on the following structured framework.
---## I. Brand DNA Lock (Immutable Constants)
| Dimension | Locked Value |
|------|--------|
| Brand Name | OATLY |
| Color DNA | Oat Grain #E8DCC8 / Forest Green #2E5C3F / Sky Blue #87CEEB / Earth Brown #8B6914 / Pure White #FFFFFF |
| Typography Temperament | English primary, Chinese secondary, Nordic minimalism, sustainable life pace |
| Brand Tone | Plant-based revolution, environmental pioneer, Nordic simplicity, lifestyle |
---## II. Image Responsibility Definition (Current Variables)
Image Type: Signature Oat Milk Main Visual / Ingredient Narrative Poster / Sustainability-Driven Brand KV
Core Task: Establish plant-based trust + Nordic minimalist feel + environmental pioneer image + lifestyle memory
Applicable Scenarios: Supermarket shelf posters / Barista collaborations / Social media environmental challenges / Sustainable living campaigns / Latte art competitions
---## III. Composition Control (Six-Dimensional Framework)
### 3.1 Perspective and Layout
- Main Perspective: Slight high-angle shot 70°-80°, slightly resembling a barista's first-person perspective
- Subject Position: Center-left of the frame, occupying 50%-60% of visual weight
- Auxiliary Element Layout: Distributed around the subject in a coffee bar style, density ≤35%
- Negative Space: Reserve 30%-35% breathing space, with appropriate white space on the right/top
### 3.2 Subject Specifications (Drink Hero)
- Core Product: One carton of OATLY oat milk (classic grey-blue packaging), or a cup of oat latte
- Packaging Texture: Matte paper carton, Nordic minimalist design in brand blue-grey tones
- Liquid Presentation: Oat milk pouring into coffee, forming natural layers, delicate foam
- Latte Art: Oat milk latte art (leaf/heart), clear edges, natural contrast
- Eco Details: Paper packaging, recyclable logos, plant-based identifiers
- Lighting Effects: Soft highlights on one side of the packaging, natural gloss on the liquid surface, creating a "pure" feel
### 3.3 Sustainable Narrative Ring (Surrounding Elements, Select 5-7 items)
| Priority | Element | Presentation Method |
|--------|------|----------|
| P0 | Oat spikes/grains (real raw materials) | Beside packaging or in background, hinting at plant-based |
| P0 | Coffee cup/milk pitcher (minimalist ceramic) | Hinting at coffee scenario |
| P1 | Biodegradable straw/wooden stirrer | Adding environmental details |
| P1 | Coffee beans (scattered, small amount) | Adding coffee atmosphere |
| P2 | Brand slogan ("WOW NO COW" very small) | Low-profile placement in corner |
| P2 | Green plant leaves (accents) | Adding a sense of nature |
| P2 | Nordic minimalist tabletop (wood/concrete) | Adding scene context |
Density Control: No more than 2 elements per category, total surrounding elements ≤ 10.
Eco Rule: All elements must be in a "sustainable" state; plastic/disposable elements are prohibited.

---## VII. Output Instruction
