marknative generates paginated PNGs without Chromium

A deterministic, lightweight alternative for generating polished documents without the massive overhead of Puppeteer or headless Chrome. It bypasses HTML and DOM to paint fragments directly using a native 2D canvas API, generating SVG output natively in under 6 milliseconds per page for blazing fast batch rendering. Built-in support for Shiki syntax highlighting and server-side MathJax makes it ideal for code-heavy LLM outputs. A deterministic layout engine ensures perfect page breaks across different environments, and it is embeddable directly via Node.js or Bun without complex browser orchestration.
