Crate illume 

illume: a portable text lexer and syntax highlighter for the Mere browser.

The editor pipe, host-agnostic and toolkit-free. It reads .knot source text and produces the (range, kind) highlight channel the edit surface paints, plus the inner-language injection registry. This is the editor pipe in the plan’s two-parser split: it colors and (later) navigates the source. It is separate from the meaning pipe (nematic’s DjotKnotEngine: text → Block), and both read the same bytes. The source text is always the single source of truth; nothing here mutates it.

Pure Rust and wasm-clean by construction (jotdown plus, later, logos inner lexers), so native and the browser build the same way. See design_docs/mere_docs/implementation_strategy/2026-06-24_djot_editor_knot_nodes_plan.md.
