AGENTS.md

+
+You are an expert in TypeScript, Angular, and scalable web application development. You write functional, maintainable, performant, and accessible code following Angular and TypeScript best practices.
+
+## TypeScript Best Practices
+
+- Use strict type checking
+- Prefer type inference when the type is obvious
+- Avoid the `any` type; use `unknown` when type is uncertain
+
+## Angular Best Practices
+
+- Always use standalone components over NgModules
+- Must NOT set `standalone: true` inside Angular decorators. It's the default in Angular v20+.
+- Use signals for state management
+- Implement lazy loading for feature routes
+- Do NOT use the `@HostBinding` and `@HostListener` decorators. Put host bindings inside the `host` object of the `@Component` or `@Directive` decorator instead
+- Use `NgOptimizedImage` for all static images.
+  - `NgOptimizedImage` does not work for inline base64 images.
+
+## Accessibility Requirements
+
+- It MUST pass all AXE checks.
+- It MUST follow all WCAG AA minimums, including focus management, color contrast, and ARIA attributes.
+
+### Components
+
+- Keep components small and focused on a single responsibility
+- Use `input()` and `output()` functions instead of decorators
+- Use `computed()` for derived state
+- Set `changeDetection: ChangeDetectionStrategy.OnPush` in `@Component` decorator
+- Prefer inline templates for small components
+- Prefer Reactive forms instead of Template-driven ones
+- Do NOT use `ngClass`, use `class` bindings instead
+- Do NOT use `ngStyle`, use `style` bindings instead
+- When using external templates/styles, use paths relative to the component TS file.
+
+## State Management
+
+- Use signals for local component state
+- Use `computed()` for derived state
+- Keep state transformations pure and predictable
+- Do NOT use `mutate` on signals, use `update` or `set` instead
+
+## Templates
+
+- Keep templates simple and avoid complex logic
+- Use native control flow (`@if`, `@for`, `@switch`) instead of `*ngIf`, `*ngFor`, `*ngSwitch`
+- Use the async pipe to handle observables
+- Do not assume globals like (`new Date()`) are available.
+- Do not write arrow functions in templates (they are not supported).
+
+## Services
+
+- Design services around a single responsibility
+- Use the `providedIn: 'root'` option for singleton services
+- Use the `inject()` function instead of constructor injection

+# YgoproCardtestWeb
+
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 21.1.2.
+
+## Development server
+
+To start a local development server, run:
+
+```bash
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
+
+## Code scaffolding
+
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
+
+## Building
+
+To build the project run:
+
+```bash
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
+
+## Running unit tests
+
+To execute unit tests with the [Vitest](https://vitest.dev/) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
+
+## Additional Resources
+
+For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.
