Lovable Prompt Creator - AI Prompt Generator

## APPLICATION OVERVIEW
This web application is a minimalist, highly functional tool designed for quoting digital manufacturing services, specifically 3D printing and laser cutting. It guides users through a step-by-step process to gather all necessary information, ensuring an efficient and user-friendly experience.

## CORE FEATURES
1. **Step-by-Step Quoting Process**: Users navigate through a clear, step-by-step interface to select manufacturing technology, materials, and parameters, ensuring a seamless quoting experience.
2. **Dynamic Material Selector**: The application adapts to the user's selections, displaying relevant materials and options based on the chosen manufacturing process.
3. **File Upload and Validation**: Users can easily upload their design files with a drag-and-drop interface, featuring real-time validation and feedback on file compatibility.
4. **Cost Breakdown and Summary**: After gathering all inputs, the application presents a detailed cost breakdown including material consumption, estimated machine time, and final pricing.
5. **PDF Generation**: Users can download a professional production sheet in PDF format, summarizing their quote for easy sharing.
6. **User-Friendly Navigation**: A fixed top navigation bar clearly indicates the current step and progress, enhancing the overall user experience.

## DESIGN SPECIFICATIONS
- **Visual Style**: minimalist - Clean, simple design with plenty of white space, minimal color palette, and focus on typography.
- **Color Mode**: Light theme with dark text on light backgrounds.
- **Primary Color**: #1978E5 (accent for buttons, links, highlights).

- **Layout**: A centered single-column layout with smooth transitions between steps, featuring a fixed top navigation bar and clearly defined sections for each step of the quoting process.

## TECHNICAL REQUIREMENTS
- **Framework**: React with TypeScript
- **Styling**: Tailwind CSS
- **UI Components**: shadcn/ui
- **State Management**: Redux (or Context API, depending on complexity)

## IMPLEMENTATION STEPS
1. **Set Up Development Environment**: Initialize a new React project with TypeScript and install Tailwind CSS for styling.
2. **Create Main Layout**: Implement the fixed navigation bar at the top with the logo, step indicator, and progress bar.
3. **Develop Step Components**: Create individual components for each of the four steps, ensuring they follow the specified layout and utilize Tailwind CSS for styling.
4. **Implement Dynamic Logic**: Use state management to handle user selections and dynamically display relevant options in the material selector.
5. **File Upload Feature**: Integrate a drag-and-drop component for file uploads, including validation logic and user feedback.
6. **Cost Calculation Logic**: Develop the backend logic to calculate costs based on user input and display a detailed summary in the final step.
7. **PDF Generation**: Implement functionality to generate and download the production sheet in PDF format once the user completes the quote.
8. **Testing and Debugging**: Thoroughly test the application across different devices and browsers to ensure a seamless user experience.

## USER EXPERIENCE
Users will start by selecting their desired manufacturing technology, followed by material choices and parameters. Each step will smoothly transition, providing clear guidance on progress. The final step will present a comprehensive summary of their quote with an option to download the information as a PDF or start a new quote. The overall design focuses on clarity and ease of use, ensuring a straightforward quoting process.
