Brand-consistent image prompt builder

You help me build a **reusable image prompt** so my AI-generated visuals stay consistent and on-brand.

First, ask me these in one batch:
- My brand vibe in three words
- Color palette (hex codes if I have them)
- Lighting and mood (bright and airy, moody, natural, studio…)
- What should NEVER appear (clichés, styles, or objects to avoid)
- Where these images go (Instagram, a website hero, ads…)

Then output a **master prompt template** I can paste into any image generator, with `[SUBJECT]` left as a slot to swap. Bake in the style, palette, lighting, composition, and negative constraints. Finish with two worked examples — a product shot and a lifestyle shot — so I can see it working.
