## Overview
#### Purpose and Scope
This is a Next.js project initialized from the standard `create-next-app` Pages Router template. Its intended purpose is a browser-facing React application with server-side API route support, although application source directories are not present in the supplied tree.
#### Entry Points
The README identifies the expected runtime entry points:
- UI page: `pages/index.js` (expected, but absent from the supplied tree).
- API endpoint: `pages/api/hello.js` (expected, but absent from the supplied tree).
- Development server: `npm run dev`, serving localhost on port 3000.
- Framework configuration: `next.config.mjs`.
The absence of `pages/` means the supplied repository snapshot cannot currently expose the documented page or API routes.
#### Application Runtime Boundary
Next.js is the primary runtime and owns request routing, React rendering, development hot reload, build output, and deployment integration. Page files under the expected `pages/` boundary become browser routes; files under expected `pages/api/` become server-side `/api/*` handlers. This separation is the core client/server boundary.
Relevant path: `next.config.mjs`.
#### Styling and UI System
The repository is configured for Tailwind CSS processing, with a component-oriented UI setup suggested by the presence of `components.json`. This indicates UI components would likely be composed in React pages rather than served as static assets.
Relevant paths:
- `tailwind.config.js`
- `postcss.config.mjs`
- `components.json`
#### Build and Dependency Layer
Node package metadata defines the executable scripts and framework dependency graph. The lockfile provides reproducible dependency resolution across local development and deployment environments.
Relevant paths:
- `package.json`
- `package-lock.json`
#### External Services and Deployment
No application-specific external APIs, databases, authentication providers, queues, or storage services are evidenced in the supplied tree. The README identifies Vercel as the recommended deployment platform; Next.js can also run in a standard Node-compatible deployment environment.
#### Repository Constraints
The README describes a conventional Pages Router structure, but the supplied tree contains only root-level configuration and package files. Before feature work or graph planning, confirm whether `pages/index.js` and `pages/api/hello.js` were omitted from the snapshot, deleted, or replaced by an unlisted application structure.
Main entry points: [`package.json`](https://github.com/thiru-88/size-suggester/blob/main/package.json) (Package scripts & dependencies), [`postcss.config.mjs`](https://github.com/thiru-88/size-suggester/blob/main/postcss.config.mjs) (PostCSS pipeline), [`package-lock.json`](https://github.com/thiru-88/size-suggester/blob/main/package-lock.json) (Locked dependencies), [`tailwind.config.js`](https://github.com/thiru-88/size-suggester/blob/main/tailwind.config.js) (Tailwind configuration)
