Instruct UI - An AI for Blazor UI Generation
## What's implemented
- Product catalog grid with search box and category filter buttons.
- Product cards (image, name, category, price, "Popular" badge) and Add button.
- Right-side cart implemented with MudTable showing item, quantity controls, unit price and line total.
- Cart calculations: subtotal, tax (configurable TaxRate), and total.
- Checkout actions: Pay & Print Receipt and Hold Order (stubs that clear cart and increment OpenOrdersCount).
- Sample in-memory data seeded in OnInitialized (GetSampleProducts).
## Key components
- MudAppBar, MudContainer, MudGrid, MudItem, MudPaper
- MudTextField (@bind-Value SearchTerm), MudButton, MudText
- MudCard, MudCardMedia, MudCardContent, MudCardActions
- MudTable<T> with HeaderContent and RowTemplate (CartItemModel)
- MudIconButton for row delete; use of @bind and @onclick-style handlers
## How it works
- Products is an in-memory List<ProductModel> populated on initialization; FilteredProducts is an IEnumerable computed from SearchTerm and SelectedCategory.
- Search uses @bind-Value on MudTextField; category buttons call OnCategorySelected to update SelectedCategory.
- AddToCart finds or creates a CartItemModel and updates Quantity; Increment/Decrement adjust quantities or remove empty items.
- Subtotal, TaxAmount and Total are computed properties based on CartItems and TaxRate.
- Event handlers (HandlePay, HoldOrder) are placeholders; they clear CartItems and increment OpenOrdersCount.
## Styling
- Primary UI uses MudBlazor components and theme tokens (Color, Typo, Variant).
- Layout uses MudGrid breakpoints (xs, md, lg) for responsive columns.
- Additional layout/spacing uses Bootstrap-like utility classes present in markup (d-flex, flex-column, gap-*, mb-*, px-*, py-*).
## Reuse steps
1. Add MudBlazor NuGet and register services: builder.Services.AddMudServices(); and include MudBlazor styles in index.html/_Host.
2. Import namespaces (using MudBlazor) in the component or _Imports.razor.
3. Copy ProductModel and CartItemModel or adapt existing domain models.
4. Place PosMainPage.razor in Pages and wire real product service instead of GetSampleProducts().
5. Implement persistence/payments: replace HandlePay/HoldOrder with calls to backend APIs, printer service, or POS middleware.
## Limitations & next steps
- Page uses in-memory sample data; no backend service, data persistence, or authentication is wired.
- Payment processing, receipt printing, and hold-order persistence are TODOs in code comments.
- Large catalogs may require paging or virtualization (MudVirtualize) for performance.
- Consider accessibility/keyboard shortcuts for POS workflows and integration with hardware (cash drawer, barcode scanner).
- Add server-side validation, error handling, and optimistic UI updates when wiring services.
