Renders a Carbon-style code screenshot as a self-contained SVG: a small in-house tokenizer colours comments, strings, numbers, keywords, types, calls, properties, tags and attributes for 20 languages (auto-detected or chosen), laid out on a monospace grid with line numbers, macOS-style window controls, an optional title, six themes and gradient backdrops with a drop shadow. Browsers that can bitmap SVG in a Worker also produce a PNG at 1–4× for download; the SVG is always available as the output. No fonts or services are fetched.
