Microsoft WebUI Framework expertise — a language-agnostic server-side rendering framework where templates compile to a binary protocol and interactive Web Components hydrate as islands. Use when authoring, reviewing, or debugging WebUI components (`.html` + `.css` + `.ts` triplets), wiring up routes, hydrating with `WebUIElement`, configuring `webui build` / `webui serve`, or integrating SSR into a backend. Also trigger when the user mentions `@microsoft/webui`, `@microsoft/webui-framework`, `@microsoft/webui-router`, `WebUIElement`, `@attr` / `@observable` decorators, `protocol.bin`, `Router.start`, `Router.navigate`, `Router.ensureLoaded`, `<route>` / `<outlet>` tags, `keep-alive`, `pending`, `cache-tags`, or shadow-DOM scoped components from Microsoft. Do NOT use for unrelated UI libraries (React, Vue, FAST standalone, Lit, Blazor, or generic Web Components projects).
