themes.js exports four extensions:
- editorLightTheme / editorDarkTheme: EditorView.theme() variants
keyed to the --cm-* CSS variables defined in tokens.css (light) and
its prefers-color-scheme: dark block.
- editorHighlightStyle: HighlightStyle bound to Lezer tags
(comment, string, number, keyword, variableName).
- editorHighlighting: syntaxHighlighting(editorHighlightStyle) ready
to drop into the EditorState extensions array.
@lezer/highlight comes in transitively via @codemirror/language;
no new package.json dependency needed.

~30 LOC StreamLanguage definition for Source-engine .cfg syntax.
Tokens: line comment (//…), string, number, keyword (exec/alias/bind/
unbindall/wait), identifier. Linewise, no nesting — matches the
shape we authored as a Prism regex grammar in the v1 attempt.
