## What's implemented
- Registration form UI with country selector, name, email, phone, password and confirm password fields.
- Country input implemented as MudAutocomplete with SearchFunc and ToStringFunc.
- Dial code selector implemented with MudSelect and MudSelectItem options.
- Password input with show/hide toggle and custom password-strength validation.
- Client-side validation using MudForm bindings, field-level Validation delegates and DataAnnotations on the model.
- Submit and reset actions with Snackbar notifications and a simulated submit flow.
- Live preview card reflecting current model state (except passwords) and responsive two-column layout using MudGrid/MudItem.
## Key components
- MudForm, MudTextField, MudAutocomplete, MudSelect, MudSelectItem
- MudButton, MudCard, MudCardHeader, MudCardContent, MudDivider
- MudGrid, MudItem, MudPaper, MudStack
- ISnackbar for notifications
- RegistrationModel, CountryModel and static RegistrationData list
## How it works
- Two-way binding uses @bind-Value and the shared RegistrationModel instance; MudForm binds IsValid and Errors via @bind-IsValid / @bind-Errors.
- Autocomplete SearchFunc returns ISO2 codes filtered by name/code and uses ToStringFunc to display the country name.
- MudSelect binds DialCode to select the country calling code; MudTextField for mobile uses a custom ValidatePhone function.
- Password field uses an InputType toggle and an OnAdornmentClick handler (TogglePassword) to switch visibility and update the icon.
- OnRegister calls form.Validate(), checks isValid, shows Snackbar messages, simulates a backend submit, resets form state and model.
- Validation is a mix of DataAnnotations on RegistrationModel and custom validation delegates (PasswordStrength, ConfirmPassword) for richer feedback.
## Styling
- Uses MudBlazor components and layout system (MudGrid / MudItem) for responsive columns (xs/md breakpoints).
- Component-level utility classes (ma-4, pa-6, mt-4, mt-6) control spacing; a few Bootstrap-style utilities (d-flex, ml-2) appear in class attributes.
- Visual theming relies on MudBlazor defaults; no Tailwind or Bootstrap layout grid required beyond small utility classes.
## Reuse steps
1. Add the MudBlazor NuGet package and register Mud services (e.g., builder.Services.AddMudServices()) in Program.cs.
2. Import MudBlazor namespace in _Imports.razor and include MudBlazor CSS and fonts in index.html/_Host.cshtml.
3. Copy RegistrationModel, CountryModel and RegistrationData into the project or replace with backend models.
4. Add the component Razor file and ensure ISnackbar is available via DI (AddMudServices registers it).
5. Replace the static RegistrationData with an injected service or API call for countries and send model to backend in OnRegister.
6. Add server-side validation, password hashing, and authentication wiring before production use.
## Limitations & next steps
- Single-page UI: no backend integration, no API calls or persistence implemented.
- Static in-memory country list in RegistrationData; replace with a service for real data and localization.
- Client-side validation complements DataAnnotations but server-side validation is required for security.
- Accessibility, rate-limited autocomplete, and stronger password storage/hashing are not included.
- Consider adding unit tests for validation logic, localization for country names, and integration with identity/auth services.
