Write Blazor UI as plain C#

BlazorCodeFirst turns a design-time Body expression into a RenderTreeBuilder method at compile time. There is no runtime UI tree, no reflection, and no runtime expression compilation — the generated component is an ordinary Blazor component.

This site is itself built with BlazorCodeFirst and published as prerendered static HTML.
