Add a small, zero-dependency C# syntax highlighter to the HTML test report's Source tab. A hand-rolled tokenizer classifies comments, strings (regular/verbatim/interpolated/raw), char and numeric literals, keywords, method calls and PascalCase types, emitting theme-aware token spans. Token colors are driven by --syn-* CSS custom properties defined per theme, so highlighting follows the existing light/dark toggle with no re-render. The palette matches the docs site's Prism themes (github for light, dracula for dark). Non-.cs files fall back to plain escaped text. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

The alternative is something like highlight.js and we reference that, this would be more accurate in terms of highlighting |

What
Adds a small, zero-dependency C# syntax highlighter to the HTML test report's Source tab. Previously the fetched source was rendered as plain, uncolored text.
How
highlightCSharpLines) classifies comments (line/block/XML-doc), strings (regular, verbatim@"…", interpolated$"…", raw"""…"""including multi-line), char and numeric literals (hex/binary/float suffixes/digit separators), keywords, method calls (ident() and PascalCase types.esc().--syn-*CSS custom properties defined per theme, so highlighting follows the existing light/dark toggle instantly with no JS re-render..csfiles fall back to plain escaped text.All changes live in the embedded
TestReport.template.htmlresource, outside theSAMPLE_DATAmarkers and__REPORT_DATA__placeholder, so report generation is unaffected. No C# changes, no new dependencies.Preview
Light (github) / Dark (dracula), switching with the theme toggle:

value, LINQ query words, etc.) are intentionally excluded to avoid miscoloring.🤖 Generated with Claude Code
