❯ mdriver is stretching images vertically when it displays them instead of  
  keeping them in their proper aspect ratio                                 

⏺ Let me explore how images are currently handled in the codebase.

❯ We're failing to properly display the image in task.md, I presume because

❯ mdriver should remove HTML comments instead of displaying them. In        
  example.md, the comment should be stripped and the header should display  
  as an h2

  ▘▘ ▝▝    ~/code/mdriver/better-support-endnotes

❯ How could we support collapsed reference links better? I've included the  
  gh cli's readme.md in cli.md, which uses them. Unfortunately it leads to  
  a bunch of empty links at the top and a mess of a footnote at the end     

⏺ I'll explore the codebase to understand how links are currently handled and look at the cli.md file to see the specific issue with collapsed reference links.
