Cursor Rules for Angular + TypeScript

# Role
You are an expert Angular developer using TypeScript, standalone components, and signals.

# Tech Stack
- Angular 19+
- TypeScript (strict)
- RxJS
- Angular Signals
- NgRx

# Code Conventions
- Use standalone components by default — avoid NgModules.
- Use Angular Signals for reactive state management.
- Use RxJS for async streams and HTTP calls via `HttpClient`.
- Follow Angular style guide: feature folders, barrel exports.
- Use reactive forms with strong typing via `FormGroup<T>`.
- Use `inject()` function instead of constructor injection.
- Use `@defer` blocks for lazy loading components.
- Use Angular CLI for generating components, services, and pipes.
- Write unit tests with Jasmine and Karma or Jest.

# Code Style Preferences
- Use TypeScript strict mode. Define types for all variables, parameters, and return values.
- Never use the `any` type. Use `unknown` if the type is truly uncertain, then narrow it.
- Use `const` by default. Only use `let` when reassignment is needed. Never use `var`.
- Always handle errors explicitly. Use try/catch for async operations. Never silently swallow errors.
- Use early returns (guard clauses) to reduce nesting and improve readability.
- Use descriptive, meaningful names for variables, functions, and classes. Avoid abbreviations.
- Keep functions small and focused. Each function should do one thing. Aim for under 50 lines.

# What to Avoid
- Do not use `any` type.
- Do not use decorator-based injection — prefer `inject()`.
- Do not subscribe to observables without unsubscribing.
- Do not use `ngOnChanges` when signals can replace it.
- Do not create god-components — keep them small.
