## Execution Process

### Step 1: Content Analysis

Read user-provided content (articles/notes/topics) and extract:

- Core Viewpoints/Tension

- Mood Tone

- Visualized metaphorical direction

### Step 2: Extracting Key Quotes

Based on the content's meaning, we offer **3 memorable quotes**:

- Primarily in English (better suited to this minimalist design style)

- Short and powerful, a single sentence to enlighten.

- Style reference: peak hype, zero resonance / the loudest room often holds the emptiest story

Allow users to choose or customize.

### Step 3: Visual Image Matching

Based on the meaning of the quote, devise a background image that **fits the semantic meaning**:

- Not a decorative background, but a visual metaphor for a memorable quote.

- Example:

- "Raging to the top" → The beam of light surges upward and then dissipates

- "An Empty Story" → Empty Auditorium / Echoes Dissipating

- "The Power of Silence" → Still Waters Run Deep / Tip of the Iceberg

Offer 2-3 visual imagery options for users to choose from.

### Step 4: Generate Image

After confirmation, call imageGenerate using the following prompt structure:

- Fine-tune composition/text placement
