====================================
Installation complete.
====================================

Next steps:
  1. Open nvim
  2. :PackerInstall   (first run — TSUpdate hook may warn; expected)
  3. :qa and reopen
  4. :PackerSync      (now TSUpdate resolves)
  5. :TSInstall <lang>  for any extra parsers
