# Style DNA

## One Sentence

Pure white, extremely minimal, hand-drawn, lots of whitespace, restrained, slightly absurd, with the feel of a product sketch, handwritten Chinese annotations, and a clear structure that does not read like an instruction manual.

Think of it as a person who has spent a long time building AI products, product systems, design systems, and developer tools, then casually drew a single explanatory sketch on white paper.

## Must-Haves

- 16:9 landscape editorial illustration
- Pure white background only: no beige, warm tones, paper grain, gradients, shadows, noise, or vintage paper feel
- Black hand-drawn line art as the primary language: thin lines, slight wobble, not mechanical, not vector-heavy, not thick outlines
- Lots of whitespace: the main subject should take about 40%-60% of the canvas, with at least 35% blank space, preferably one clear quiet area
- A small amount of handwritten Chinese annotations: at most 5-8 locations, each label ideally 2-8 characters
- One image should explain only one core action, structure, state, or metaphor
- Structure should feel natural and not label itself in the image

## Color

- Black: main lines, characters, frames, structure, primary text, main objects
- Red: emphasis, warning, problem, key reminder, result
- Orange: main path, route, arrows, movement from A to B
- Blue: extra explanation, internal state, system state, second-layer interpretation, AI/assistant/automation cue

Blue is not required on every image. Use color sparingly and keep the palette disciplined.

## Absolute No's

- No commercial illustration
- No PPT infographics
- No formal flowcharts
- No course slides
- No cute mascot poster
- No children's illustration
- No complex architecture diagrams
- No polished flat illustration
- No tech UI screenshot
- No realistic app screenshot
- No paper texture, gradients, shadows, or noisy background
- No long explanatory text in every section
- No top-left labels such as "Workflow", "System Architecture", "Common Pitfalls", or "Roadmap"

## Aesthetic Direction

The work should feel weird, creative, clean, and slightly absurd.

Do not make it cute, childish, overcomplicated, or dead.
