The Hero Image Concept Generator

#ACTION
Write three image-generation prompts for a hero image. Each prompt must produce a visually distinct direction so I can compare and pick. Output prompts optimized for {{image model — e.g., Midjourney v6, DALL-E 3, Stable Diffusion XL}}.

#PURPOSE
I need a hero image for {{your product/landing page}}. The image sits above the fold and has 2 seconds to communicate what this is before the visitor scrolls.

#EXPECTATION
For each concept, provide:
1. **Concept name** — 2-3 words labeling the visual direction.
2. **The generation prompt** — a complete, paste-ready prompt string for the specified model, 30-60 words.
3. **Why this direction** — one sentence on what feeling or message it sends.
4. **Negative prompt** (if the model supports it) — what to exclude.

The three directions must be meaningfully different (e.g., abstract gradient, realistic product-in-environment, isometric illustration). Not three variations of the same idea.

Rules for each prompt:
- Specify composition (where the subject sits, where the negative space is for text overlay).
- Specify lighting and color palette tied to the brand mood.
- Specify aspect ratio (16:9 for most hero sections).
- No text in the image — text will be overlaid in HTML.

Brand context: {{brand colors, mood, one-line value prop}}
