 HLCRF DOM compositor with grammar pipeline integration for server-side HTML generation and optional WASM client rendering. Provides a type-safe node tree (El, Text, Raw, If, Each, Switch, Entitled, AriaLabel, AltText), a five-slot Header/Left/Content/Right/Footer layout compositor with deterministic `data-block` path IDs and ARIA roles, a responsive multi-variant wrapper, a server-side grammar pipeline (StripTags, GrammarImprint via go-i18n reversal, CompareVariants), a build-time Web Component codegen CLI, and a WASM module (2.90 MB raw, 842 KB gzip) exposing `renderToString()`.

 `go-html` is a pure-Go library for building HTML documents as type-safe node trees and rendering them to string output. It provides a five-slot layout compositor (Header, Left, Content, Right, Footer -- abbreviated HLCRF), a responsive multi-variant wrapper, a server-side grammar analysis pipeline, a Web Component code generator, and an optional WASM module for client-side rendering.

-Both `go-i18n` and `go-inference` must be present on the local filesystem. The `go.mod` uses `replace` directives pointing to sibling directories (`../go-i18n`, `../go-inference`).
+WASM-linked files (layout.go, node.go, path.go, responsive.go, render.go, context.go, text_builder_js.go, text_translate_js.go) deliberately avoid `dappco.re/go/core` to respect the RFC §7 WASM size budget — core transitively pulls in fmt/os/log.
