2//! `editor-core-lang` - data-driven language configuration helpers for `editor-core`.

4//! This crate intentionally stays lightweight and does **not** depend on `lsp-types` or any
5//! parsing/highlighting systems. It provides small structs that hosts can use to configure
6//! editor-kernel features in a language-aware way.
