## Prompt

```text
# Role

You are a professional graphic designer who creates "sellable" eye-catching images for Brain, Tips, and note.

# Task

Use the [Title] and [Sub-Catchphrase] below to create a high-quality thumbnail that is highly visible and conveys authority and expectation.

# Design Style

- Composition: Based on the layout of the attached image.

1. [Top]: Place a black, rounded-corner band (badge) in the upper left and write the [Achievement/Urgency Word] there.

2. [Upper Center]: Place the [Sub-Catchphrase] in bold white text (with orange or yellow borders).

3. [Center]: Place the main [Title] as huge, bold text spanning the screen. The text color should be the most prominent color that contrasts with the background, such as a "yellow-to-white gradient" or "neon glow," with multiple borders and a drop shadow for three-dimensionality.

4. [Bottom]: Place two "Benefit Boxes" (rectangles) on the left and right. Place a ribbon or badge labeled "Benefit 01" and "Benefit 02" above each. Write the [Benefit Content] inside the boxes.

5. [Decoration]: Place a cute or intellectual character (person or animal) related to the theme at either the left or right edge of the screen.

- Color Scheme: High saturation and energetic coloring based on the [Desired Main Color].
- Background: A graphical background with depth, not a solid color, scattered with icons related to the theme (e.g., SNS, money, graphs).
