Subject: [PATCH] kyber: document registry fix for Origin language error and
 GPU crash workaround
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add troubleshooting for 'Origin Error: title installed in language not
  entitled to play' — Maxima's umu-run reg commands fail silently on some
  systems; manual wine64 regedit import of Origin locale keys fixes it
- Add windowed-mode / HDR fix for SWBF2 crash during level load on
  integrated GPUs (Intel Iris Xe, DXVK rendering crash)
- Document fix in both README.md and script header comments
