pub fn apply_syntax_highlighting(
code: &str,
lang: &str,
) -> Result<String, MarkdownError>Expand description
Highlights a code string with class-based spans (standalone API).
This is the public entry point for callers who want to highlight
code outside of the markdown pipeline. Output is a sequence of
<span class="…"> tags — pair it with theme_css to produce
a stylesheet that renders the colours.
