MudBlazor Login Form that provides Usuario and Password fields with client-side validation and error alerts. Uses MudForm and MudTextField inside a MudCard and applies Bootstrap utility classes for layout.

## What's implemented - Centered login card containing Usuario and Contraseña fields. - Client-side validation with MudForm and field-level required messages. - Error area displayed with MudAlert for form-level messages. - Action button to trigger validation and (placeholder) submit logic. ## Key components - MudForm (@ref Formulario, @bind-IsValid, @bind-Errors) - MudTextField (T="string", @bind-Value for Modelo.Usuario and Modelo.Password) - MudAlert (Severity.Error) for error display - MudButton for submit action - MudCard, MudCardContent, MudCardActions, MudGrid, MudItem, MudContainer ## How it works - The page binds a LoginModel instance to two MudTextField controls using @bind-Value. - MudForm is referenced via @ref and exposes validation state via @bind-IsValid and @bind-Errors. - OnIngresarClick calls Formulario.Validate(), checks EsValido and populates Errores when validation fails. - Submit logic is a placeholder; real authentication, NavigationManager or API calls are not wired. ## Styling - UI uses MudBlazor components for structure and theme-ready controls. - Bootstrap utility classes (d-flex, justify-content-center, mb-3, p-4) are applied for centering and spacing. - The layout is responsive through MudContainer/MudGrid; MudBlazor theming controls visual density. ## Reuse steps 1. Add MudBlazor to the project (NuGet MudBlazor) and register services (builder.Services.AddMudServices()). 2. Import MudBlazor namespace where needed and include MudBlazor CSS in index.html/_Host.cshtml. 3. Copy LoginPage.razor and LoginModel, adjust property names and localization as required. 4. Inject NavigationManager and an authentication service to replace the placeholder submit logic. 5. Wire server-side validation or API calls and handle tokens/state in a central auth service. ## Limitations & next steps - Page contains only front-end validation; no authentication API, token handling, or state management is implemented. - NavigationManager is commented but not injected; add DI and success navigation. - Consider adding DataAnnotations or custom validators, loading indicator on submit, and accessibility attributes. - Integrate with an authentication service and protect routes after successful login.
