# Extension: Rendering Rendering traits control how pages are composed, how templates are provided, how template context is extended, and how static pages are pre-generated. All traits live in `crates/shared/provider-contracts/src/`. --- ## 1. ComponentRenderer Renders reusable UI components (header, footer, sidebar, partials) into page templates. ### Trait ```rust #[async_trait] pub trait ComponentRenderer: Send + Sync { fn component_id(&self) -> &str; fn applies_to(&self) -> Vec<String>; fn partial_template(&self) -> Option<PartialTemplate>; async fn render(&self, ctx: &dyn ComponentRenderContext) -> Result<RenderedComponent>; } ``` ### Existing Components | Component | Renderer | Pages | |-----------|----------|-------| | Head assets | `HeadAssetsPartialRenderer` | All | | Header | `HeaderPartialRenderer` | All | | Footer | `FooterPartialRenderer` | All | | Scripts | `ScriptsPartialRenderer` | All | | CLI animation | `CliRemoteAnimationPartialRenderer` | Homepage | ### Registration ```rust impl Extension for MyExtension { fn component_renderers(&self) -> Vec<Arc<dyn ComponentRenderer>> { vec![Arc::new(MyComponent)] } } ``` --- ## 2. TemplateProvider Supplies page templates (embedded or file-based) for rendering. ### Trait ```rust pub trait TemplateProvider: Send + Sync { fn templates(&self) -> Vec<TemplateDefinition>; fn provider_id(&self) -> &'static str; fn priority(&self) -> u32; } ``` ### Priority System | Pr
