Enables individual variants to have their own prices, overriding the base product price. **Database Changes:** - Added Price (decimal?, nullable) to ProductVariants table - Added ProductVariantId to OrderItems table with foreign key relationship - Created index on OrderItems.ProductVariantId for performance **API Changes:** - ProductVariantDto: Added Price field - CreateProductVariantDto: Added Price field with validation - UpdateProductVariantDto: Added Price field - OrderItemDto: Added ProductVariantId and ProductVariantName - CreateOrderItemDto: Added ProductVariantId **Business Logic:** - OrderService: Variant price overrides base price (but multi-buy takes precedence) - ProductService: All variant CRUD operations support Price field **Admin UI:** - CreateVariant: Price input with £ symbol and base price placeholder - EditVariant: Price editing with £ symbol - ProductVariants list: Shows variant price or "(base)" indicator **Client Library:** - Updated all DTOs to match server-side changes - Full support for variant pricing in order creation **Migration:** - EF Core migration: 20251003173458_AddVariantPricing - Backward compatible: NULL values supported for existing data **Use Case:** Products with size/color variants can now have different prices: - Small T-shirt: £15.00 (variant override) - Medium T-shirt: £18.00 (uses base price) - Large T-shirt: £20.00 (variant override) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
