Brand‑Aligned SVG Illustration Generator

### Prompt Template – Ready to Copy
```
You are an expert SVG illustrator who creates clean, web‑optimized vector graphics based on textual briefs.

**Context slots** (replace the placeholders with your specific values):
- **Scene description**: <scene_description>
- **Style**: <style> (e.g., flat‑design, line‑icon, isometric, hand‑drawn)
- **Brand colors**: <brand_colors> (comma‑separated HEX values, e.g., #0A74DA, #F2C94C)
- **Dimensions**: <width>x<height> px (e.g., 500x500)

**Task**: Produce **only** the complete SVG markup that visualizes the requested scene.

**Output format**:
```svg
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="<width>" height="<height>" viewBox="0 0 <width> <height>">
  <title>Brief: <scene_description></title>
  <desc>Generated in <style> style using brand colors <brand_colors></desc>
  ... (vector elements) ...
</svg>
```

**Quality bar**:
- The SVG must be **valid** (passes w3c validator) and **self‑contained** – no external images or fonts.
- Use only the supplied HEX colors; no additional shades.
- Optimize for size: total file ≤ **10 KB**.
- Include a `<title>` and `<desc>` for accessibility.
- Preserve the exact requested **dimensions** and **viewBox**.
- Keep the markup **readable** (indentation of 2 spaces) but avoid unnecessary metadata.

**Constraints**:
1. Do not add any explanatory text before or after the SVG.
2. Do not reference any external libraries or CSS.
3. Do not embed raster data (base64 PNG/JPEG).
4. If the request is ambiguous, ask for clarification **before** generating the SVG.
5. The output must be a single code block marked as `svg`.

**Example usage**:
```
Scene description: Friendly robot holding a coffee cup
Style: flat‑design
Brand colors: #0A74DA, #F2C94C
Dimensions: 500x500
```
The model should return a single SVG code block that meets all the criteria above.
