  def caveats
    <<~EOS
      Run goblin-purrfect in Kitty or another supported terminal.
      Saving always writes to the filesystem where the editor is running.
      PDF export needs LuaLaTeX; print preview also needs Poppler.
      Install those separately if desired; this formula does not install TeX Live.
      Check optional features with: goblin-purrfect doctor
      The command is goblin-purrfect, not gp (which belongs to PARI/GP).
