# GitHub Copilot Instructions

Use this file to guide GitHub Copilot in this repository.

## Project Context

- Project type: Next.js

## Project Commands

## Working Agreement

- Read nearby files and reuse established project patterns.
- Make small, reviewable changes.
- Do not introduce new dependencies unless they clearly reduce complexity.

## Validation

1. Run `npm run lint` for style and static checks.
2. Run `npm test` for behavior.
3. Run `npm run build` before release or handoff.

## Extra Instructions

Before handoff, summarize changed files and mention any checks that could not be run.
