产品技术拆解信息图：工程注释风格产品解剖图

Create a branded technical infographic of a premium chocolate bar, combining a realistic photograph or photoreal render of the product with technical annotation overlays placed directly on top. Use black ink-style line drawings with strategic warm gold accents (architectural sketch look) on a pure white studio background, including:

- Key component labels
- Internal cross-section showing structure, layering, or internal design
- Measurements, dimensions, and specifications
- Material callouts with composition and quantities
- Arrows indicating function for primary features and structural integrity
- Simple schematic or sectional diagram showing key mechanical or design elements
- Sustainability callouts

Title placement: Inside a hand-drawn technical annotation box with accent border reading the product name in bold font, positioned in upper corner.

Style & layout rules:
- The realistic product remains clearly visible
- Annotations feel sketched, technical, and architectural
- Accents used for highlight (20-30% of linework), black for primary technical lines (70-80%)
- Clean composition with balanced negative space
- Educational, food-engineering vibe with premium branding
- Include subtle brand logo mark in corner

Visual style: Minimal technical illustration aesthetic, black linework with accents over realistic imagery, precise but slightly hand-drawn feel.

Color palette: White background, black annotation lines/text, brand color for accents and key callouts only.

Output: 1080x1080 square, ultra-crisp, social-feed optimized, no watermark
