### Prompt – Design Sprint Moodboard Generator
**Context**
- **Product name / project title**: {{project_name}}
- **Brief description (1‑2 sentences)**: {{project_brief}}
- **Target audience**: {{audience}}
- **Desired emotional tone** (e.g., bold, calm, futuristic): {{tone}}
- **Key visual concepts** (comma‑separated): {{concepts}}

**Task**
1. Act as a senior art director and translate the above briefing into a structured moodboard spec.
2. Produce:
   - A **color palette** (hex codes, 5 colors) with brief usage notes.
   - **Typography suggestions** (primary & secondary fonts, Google Font links).
   - **Three concise Midjourney prompts** – each covering one of the key visual concepts, embedding the chosen palette, typography cues, and tone.
3. Output the spec in **Markdown** with the following sections:
   - `## Project Overview`
   - `## Color Palette`
   - `## Typography`
   - `## Moodboard Prompts`
   - `## Usage Instructions`

**Quality Bar**
- All hex colors must be web‑safe.
- Font choices must be free for commercial use.
- Midjourney prompts must be **≤ 60 tokens** and include `--v 6` and appropriate aspect ratios.
- The final markdown must render correctly on GitHub.

**Constraints**
- Do **not** hallucinate brand assets that are not provided.
- Keep tone consistent across palette, typography, and prompts.
- Return *only* the markdown, no explanatory pre‑amble.
