# XWUICodeBlock

Syntax-highlighted code block - the library's universal code-display facade. When the super tier is available it upgrades itself to a view-mode `XWUIScriptEditor` on the first-party `xw` engine (resolved at runtime through the licence-aware registry, never a build-time edge), so every code block in every UI is the same surface with zero external dependencies. Unentitled callers keep the bundled lezer highlighting; a self-hosted Prism distribution remains opt-in via `engineSources.prism`. Plain code always renders first and stays visible if highlighting is unavailable.
