Cursify is a Next.js application that serves as both a documentation site and a component library for custom cursor animations and background patterns. It provides over 30 cursor effects (e.g., fluid, neon, blob, fairy dust, glitch) and 12+ pattern animations (e.g., flowing dots, vertical bars, sliding ease), each with live previews, code snippets, and installation instructions. The architecture is a static Next.js site using the App Router, MDX for content, and a registry of reusable React components. The codebase is well-organized with separate directories for hooks, UI primitives, and registry components. It relies on several animation libraries (Framer Motion, react-spring, motion) and Radix UI for interactive elements. The primary data flows are static: MDX content is rendered server-side, and client-side interactivity is handled via React hooks and canvas/WebGL. There is no backend or API; the site is purely a documentation and showcase platform.
