title: Puppeteer PDF Title and Author (metadata)
body: <p>After all my searches and code digging didn't help, I'm asking here for a hint:</p>
  
  <p>How, using Puppeteer PDF generation, do I set the metadata of the file (specifically title and author)?</p>
  
  <p>I've tried setting meta tags in my HTML, but it didn't output these into the file metadata.</p>
