[martinvibes]

📚 Overview
This pull request introduces the complete "Manage Content" experience for ChainLib, enabling authors to seamlessly create, edit, view, and manage both their publications and associated NFT editions. The implementation is based on the latest Figma designs and aims to deliver a polished, responsive, and accessible experience that integrates backend APIs, blockchain interactions, and modern form handling. This is a major feature in the ChainLib roadmap and a key piece in empowering creators on the platform.

🧩 Key Features & Functionality

• Dynamic Routing: Utilized Next.js file-based routing to support multiple views and dynamic pages for managing publications and editions. This includes pages like create, edit, and view with appropriate modals and dialogs.
• Pixel-Perfect UI: Every component closely follows the Figma design system, including proper spacing, typography, and visual feedback. The layout is fully responsive and supports both desktop and mobile breakpoints.
• Accessibility Compliance: Interactive components such as buttons, dialogs, and inputs adhere to accessibility best practices, ensuring keyboard navigation and screen reader support.
• Full CRUD Support: Authors can create new publications, update metadata or editions, delete entries, and manage NFT minting and updates through a unified interface.
• 🔗 Blockchain Integration: Leveraged wagmi and ethers.js to handle NFT minting/editing logic, including wallet interaction, transaction feedback, and error handling.
• Form Handling: Implemented all forms using React Hook Form with detailed validation schemas, user-friendly error messages, and submission state management.
• Smooth UX Transitions: Framer Motion was used to animate transitions between steps, pages, and modals for a polished user flow.
• Tested User Flows: All actions (create, edit, view, delete) have been tested to ensure stability and correctness across screen sizes and usage scenarios.
