手绘涂鸦提示词 .

A professional technical hand-drawn illustration about: ${topic}. This image must be a PORTRAIT (3:4 aspect ratio) to allow for a tall, detailed vertical flow. VISUAL STYLE RULES (STRICT): 1. Drawing Style: Hand-drawn doodle, marker sketch, thick black ink outlines. No 3D, no realistic textures. 2. Background: Solid plain white (#FFFFFF). 3. Color Palette: Minimalist. ONLY Black, White, and soft "Pale Yellow" (#FFF9C4) for highlights. 4. Icons: Simple, recognizable doodles (e.g., CPU, Database, Browser, Person, Cog). 5. Text: Hand-written font style. Technical terms and code in light-yellow highlight boxes. LAYOUT & LOGIC (FLEXIBLE VERTICAL FLOW): - DO NOT force a strict left-vs-right split. Instead, design a "Problem vs. Solution" comparison that extends VERTICALLY down the page. - The layout should be optimized based on the content to maximize clarity. - Examples: - For sequential steps: Use a vertical chain (Problem top, Solution bottom). - For system architecture: Use a top-down stack comparison. - Only use a partial left-vs-right if the content is very simple and balance allows. - In all layouts, ensure the "Problem/Old/Slow" state uses stressed icons and chaotic arrows, while the "Solution/New/Optimized" state uses calm, organized, and streamlined vertical flows with specific code/logic. BRANDING & COPYRIGHT (MANDATORY): - In the bottom-right corner, neatly hand-write the signature: "© TiHUBB". - The signature should be subtle, small, and integrate perfectly with the doodle style.
