Build an AI storyboard generator web app with these features: 1. Script import: paste or upload a script (Fountain or plain text) and the AI breaks it into numbered scenes with location, time of day, and characters. 2. Shot breakdown per scene with suggested framing (wide, medium, close-up, insert), camera movement notes, and duration. 3. Frame generation: for each shot, generate an illustration via an image API from a prompt that includes scene setting, characters, and framing, with a style picker (sketch, ink, photoreal, flat vector). 4. Character sheets: define each character once (description plus reference image) and reference them in every frame prompt to reduce drift, with a regenerate button per frame. 5. Dialogue and action captions under each frame, editable inline. 6. Shot list table view: shot number, scene, framing, movement, duration, equipment notes, exportable to CSV. 7. Drag-and-drop frame reordering and multi-frame selection for bulk regenerate. 8. Client-ready export: branded PDF storyboard with scene headings, frames, captions, and revision history, plus a share link with comment pins per frame. 9. Versioning: duplicate a project as a take, compare takes side by side. 10. Team plan with per-project roles (editor, viewer, commenter).
