-This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in `node_modules/next/dist/docs/` (resolved from this file's directory; in monorepos the `next` package may not be visible from the repo root) before writing any code. Heed deprecation notices.

-This block is written and re-added by `next dev` — verify at `node_modules/next/dist/server/lib/generate-agent-files.js`. Removing it from a diff only re-creates the uncommitted change; committing it with your work keeps the tree clean.

 ## Getting Started
 
 ### Prerequisites
 
 - Node.js 24.5 (matches CI).
 - pnpm 11.10.0 — pinned via `packageManager` in `package.json`; `corepack enable` will pick it up automatically.
-- A running [`algowars/server`](https://github.com/algowars/server) API, unless you're pointing `NEXT_PUBLIC_API_SERVER_URL` at a shared dev environment instead. See [`playwright/README.md`](./playwright/README.md#prerequisites) for the local Postgres/RabbitMQ/API bootstrap steps.
+- A running [`stack-duel/server`](https://github.com/Stack-Duel/server) API, unless you're pointing `NEXT_PUBLIC_API_SERVER_URL` at a shared dev environment instead. See [`playwright/README.md`](./playwright/README.md#prerequisites) for the local Postgres/RabbitMQ/API bootstrap steps.
 
 ### Installation

 And this will make a copy of the empty .env file. Then fill in:
 
 - `AUTH0_*` — go into Auth0 and create a Next.js web application and an API, then fill in the resulting values. `AUTH0_SECRET` can be generated with `openssl rand -hex 32`.
-- `NEXT_PUBLIC_API_SERVER_URL` — where the `algowars/server` API is reachable (`http://localhost:5041` for a locally-running instance).
+- `NEXT_PUBLIC_API_SERVER_URL` — where the `stack Duel/server` API is reachable (`http://localhost:5041` for a locally-running instance).
 - `NEXT_PUBLIC_CODEPREVIEW_ORIGIN` — the origin serving the React-component-preview iframe runtime (see `codepreview/`). This is **required**: the app throws on startup if it's unset. Unless you're specifically working on that feature, point it at the shared dev deployment — ask a teammate for the current URL, or check the `Preview` GitHub Environment's variables.
 - `NEXT_PUBLIC_APPLICATIONINSIGHTS_CONNECTION_STRING` is optional — telemetry is skipped when it's unset.
