🔴 React component added to an Angular project — incompatible framework

The new Loader.tsx is a React component (import React from 'react', React.FC, JSX) being added to a project that is entirely Angular 9. The project uses @angular/core components (src/app/shared/components/loader/loader.component.ts), Angular CLI for building (angular.json), and tsconfig.json has no "jsx" compiler option, so .tsx files cannot be compiled. Additionally, CSS modules (.module.css) are a React/webpack pattern not supported by Angular CLI's build pipeline. The project already has a working Angular loader at src/app/shared/components/loader/. This component will not compile and cannot be used anywhere in the application.

Prompt for agents 
The Loader.tsx file is a React component being added to an Angular project. The entire codebase uses Angular 9 (see package.json for @angular/* dependencies, angular.json for build config, and all existing components under src/app/ using @Component decorators).

The project already has an equivalent Angular loader component at src/app/shared/components/loader/loader.component.ts with its template at loader.component.html and styles at loader.component.scss.

To fix this, either:
1. Remove the React component entirely since the Angular equivalent already exists, OR
2. If new loader functionality is needed, create it as an Angular component following the existing pattern: use @Component decorator, .component.ts/.component.html/.component.scss files, and place it under src/app/ following the project's directory conventions.

This is intentional — the PR follows the Angular to React migration playbook which explicitly requires:

  1. Creating the React equivalent alongside the Angular component
  2. Not removing the Angular component

The React component is placed under src/components/ (separate from src/app/) as specified in the task. Integration into the build pipeline (adding JSX support, wiring imports, etc.) is a separate step outside the scope of this 1:1 component migration.
