[FedeAntunes]

You are a senior software engineer. Implement the following technical specification.

OBJECTIVE

Add a simple log message that greets when the app starts up.

SCOPE

In scope

• Modify the app bootstrap file src/main.tsx to include a console log greeting on app startup
• Ensure the log appears once when the React app is initialized
• Follow existing code conventions and formatting rules

Out of scope

• Adding complex logging infrastructure or external logging services
• Changing any UI components or pages
• Modifying authentication or API logic
• Adding tests for this trivial logging change

TECHNICAL CONTEXT

• The app is a React 18 SPA bootstrapped with Vite, entry point is src/main.tsx
• TypeScript 5 is used throughout the codebase
• The app uses React.StrictMode and global providers configured in src/app/providers
• Logging should be done via console.log for simplicity
• Code formatting conventions: 2 spaces indentation, printWidth 110, organize imports on save
• No barrel exports should be created or modified
• The app supports optional MSW mocking enabled via enableMocking() in main.tsx
• The app uses environment variables mapped in src/app/config/env.ts but none are needed for this task

CONSTRAINTS

ASSUMPTIONS

• The log should be a simple console.log statement with a friendly greeting message
• The log should appear only once when the app is launched
• No additional dependencies or packages are required
• The change should not affect app functionality or user experience

ACCEPTANCE CRITERIA

• When the app starts, the browser console shows a greeting log message
• The greeting log appears only once per app load
• The app continues to function normally without errors
• Code changes follow the project's formatting and import conventions

EXECUTION PLAN

• Open src/main.tsx where the React app is bootstrapped
• Add a console.log statement with a greeting message before or after the ReactDOM.render or createRoot call
• Ensure the log message is clear and friendly, e.g. 'Hello! App has started.'
• Verify no other code is affected and formatting rules are respected
• Run the app locally with yarn dev and confirm the log appears once in the browser console
• Commit the change with a descriptive message referencing the task

RISK AREAS

• Minimal risk as this is a non-intrusive console log addition
• Potential for multiple logs if placed inside components or hooks instead of the bootstrap file
• Ensure no accidental side effects or import changes occur

OUTPUT REQUIREMENTS

• Produce working code (no pseudocode)
• Keep changes minimal and aligned to existing architecture
• Add/adjust unit tests where appropriate
