README exists and is adequately maintained

A missing or boilerplate README means the first developer to clone your project — or you on a new machine six months from now — must read source code to discover how to install dependencies, configure environment variables, and start the server. ISO 25010 maintainability.analysability fails at the project entry point. An unmodified create-next-app README is indistinguishable from a project with no documentation at all: it describes Next.js, not your project. Every undocumented setup step is a blocker for every future contributor.

Write a minimum viable README covering what the project does, how to install it, and how to run it. Reference src/app/ for the route structure and call out non-obvious setup steps:

# Project Name

One paragraph: what this does and who it's for.

## Setup
1. `npm install`
2. Copy `.env.example` to `.env.local` and fill in the values
3. `npm run dev` — runs on http://localhost:3000

## Project Structure
- `src/app/` — routes and pages
- `src/components/` — shared UI components
- `src/lib/` — utilities and third-party wrappers

Fifteen minutes of writing now saves hours of onboarding friction later.
