+# Prompt Writing Rules
+
+Rules for generating high-quality image generation prompts. Apply these when writing the final prompt in Step 5.
+
+## 1. Visual Precision
+
+Always describe:
+
+- **Background texture** (e.g., off-white aged paper, black halftone shadows, light gray grid texture)
+- **Font style** (e.g., handwritten, serif print, colorful block-lettering, monospace technical)
+
+Omitting these causes the image model to make arbitrary choices that undermine the intended aesthetic.
+
+## 2. Color Avoidance
+
+Never use hexadecimal color codes (`#RRGGBB` format). Use specific color names instead.
+
+| Instead of | Use |
+|------------|-----|
+| `#FF6B6B` | coral red |
+| `#2D3748` | deep slate gray |
+| `#F6E05E` | warm yellow |
+| `#68D391` | sage green |
+
+## 3. Text Citation
+
+All copy intended to appear as text in the image must be enclosed in `"double quotes"`.
+
+- Correct: a bold label reading `"Step 1: Define the Problem"`
+- Incorrect: a bold label reading Step 1: Define the Problem
+
+This lets the image model distinguish between descriptive instructions and literal text to render.
+
+## 4. Arrow Minimalism
+
+Minimize the use of arrows. Prefer spatial proximity to imply flow and connection.
+
+When arrows are necessary:
+
+- Specify exact **start point** and **end point** (e.g., "an arrow from the 'Input' box pointing to the 'Process' box")
+- Never use vague orientations like "a horizontal arrow" or "a vertical arrow"
+
+## 5. Semantic Correspondence
+
+Every icon, illustration, or decorative element must correspond semantically to the adjacent text content. Avoid generic decorative elements that could apply to any topic.
+
+## 6. Punctuation Hygiene
+
+Never use quotation marks when describing:
+
+- Style (e.g., write: flat design aesthetic — not: "flat design" aesthetic)
+- Layout structure (e.g., write: three-column grid — not: "three-column grid")
+- Colors or textures
+- Moods or feelings
+
+Quotation marks are reserved exclusively for **Rule 3: Text Citation**.
+
+## 7. Step Granularity
+
+If the content contains stages, steps, or a sequence:
+
+- Detail **every single step** individually
+- Never merge or compress multiple steps into one
+- Each step gets its own visual element and label
+
+## 8. Data & Encoding
+
+All hard data from the source must be:
+
+- Preserved **verbatim** — no paraphrasing of numbers, dates, or proper nouns
+- Presented in a visually distinct format: bold text, labeled callout boxes, sticky notes, or data badges
