Motivation

• Provide a minimal monorepo scaffold for an AI Image Studio MVP to enable fast local development and integration testing.
• Offer a mockable generation backend and in-memory job queue so the web UI can exercise generation, progress, and cancel flows without a real model provider.
• Deliver a simple Next.js workbench UI that demonstrates generation controls, queue/status polling and result previews.
• Include a lightweight worker and documentation to illustrate how the pieces run together locally.

Description

• Add root monorepo configuration and workspace layout, plus a .gitignore and per-app package.json files to host apps/api, apps/web, and apps/worker.
• Implement a mock API in apps/api with an express server, JobStore (in-memory), JobService (simulated progress + outputs), a mock provider in apps/api/src/providers/mock.ts, and OpenAPI docs served at /docs.
• Ship a Next.js web UI in apps/web that posts generation jobs, polls job status, displays queue/history, and includes styling in apps/web/styles/globals.css.
• Add a simple worker poller in apps/worker and a unit test apps/api/tests/job-store.test.ts, along with docs/INSTALL.md describing local install and run commands.

Testing

• Attempted npm install for the workspace, but the install failed due to a 403 Forbidden error from the npm registry so dependencies were not installed.
• Because npm install failed the automated test runner (vitest) was not executed and no tests were run.
• A unit test is provided at apps/api/tests/job-store.test.ts, ready to run once dependencies are available.
• Local run instructions are documented in docs/INSTALL.md and recommend npm run dev:api and npm run dev:web to start the stack.
