Build an AI mood board generator web app with these features:

1. Text prompt input where users describe their project: brand mood, industry, target audience, visual style keywords. Example: 'Minimalist wellness brand targeting professional women, soft earth tones, organic shapes, calm and grounded feeling.'

2. AI image generation: generate 6 to 12 images per mood board using DALL-E or Stable Diffusion API, tailored to the prompt. Images span categories: lifestyle photography, product shots, texture and material, abstract patterns, and environment.

3. Color palette extraction: AI analyzes generated images and extracts a 5-color palette with hex codes. Users can lock colors and regenerate images to match. Palette can be exported as CSS variables, SCSS, or Adobe ASE file.

4. Typography suggestions: AI recommends 3 font pairings (heading and body) from Google Fonts that match the mood. Shows preview text in each pairing with download links.

5. Drag-and-drop canvas where users arrange images, color swatches, and text on a free-form board. Resize, rotate, layer, and group elements. Snap-to-grid option for clean layouts.

6. Inspiration library: save and categorize mood boards by project. Browse a public gallery of community mood boards for inspiration. Filter by industry, color, style.

7. Export options: PNG image, PDF document, shareable web link with password protection, and embed code for portfolio sites.

8. Brand brief generator: AI writes a short brand direction document based on the mood board, covering visual direction, color psychology, typography rationale, and recommended photography style.

9. Iterative refinement: users can add more prompt keywords, request 'more of this' on any image, swap individual images, or ask AI to 'make it warmer/cooler/more minimal/bolder.'

10. Team collaboration: share mood boards with clients or team members for feedback. Comment and annotation system directly on the canvas.
