笔记本电脑技术信息图插画

Create a square technical infographic of a {argument name="subject" default="laptop"}, combining a realistic product photograph or photorealistic render with precise annotation overlays drawn directly over the device.

Use a pure {argument name="background color" default="white"} studio background and {argument name="ink color" default="black"} ink technical linework, like an architectural sketch or engineering manual. Include:
- Key component labels
- Internal cutaway details or exploded-view outlines
- Measurements, dimensions, and scale markers
- Material callouts and quantity notes
- Arrows showing function, airflow, power flow, sound path, pressure, or other relevant system behavior
- Simple schematic or sectional diagrams where useful

Place the title "LAPTOP" inside a hand-drawn technical annotation box in one corner.

Style and layout rules:
- The realistic laptop must remain clearly visible beneath the annotations
- The annotations should feel sketched, technical, and architectural
- Keep the composition clean with balanced negative space
- Make it feel educational, like a museum exhibit panel or engineering manual page

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

Color palette:
White background with black annotation lines and black text only. No colors.

Output:
1080 x 1080, ultra-crisp, optimized for a social feed, no watermark.
