 #### **Blackwell Architecture & CUDA v590**
 - **Detection**: `_helpers.sh` function `is_nvidia_blackwell()` identifies GPUs via PCI IDs `10de:24xx`, `0x2900–0x29BF`, and `0x2B80–0x31FF`.
 - **Reason for v590**: Debian 13 (Trixie) stable drivers only support up to v550, which lacks Blackwell (GB20x) architecture. The NVIDIA CUDA repository provides production branch v590 with unified driver packages. Specifically, the goal is to install the latest version of the nvidia-driver from the 590 branch, which would be [590.48.01](https://download.nvidia.com/XFree86/Linux-x86_64/590.48.01/README/supportedchips.html).
-- **CUDA Repository Enablement**: On Debian 12 (Bookworm) the `nvidia-cuda` repository is enabled via `extrepo`. On Debian 13 (Trixie) the official `cuda-keyring` package is used instead (`wget` + `dpkg -i`), since extrepo cannot configure the repo correctly on Trixie. After enabling, the script always runs an explicit `apt update` and verifies the APT candidate matches the requested branch (`595.*`) before writing APT pinning in `/etc/apt/preferences.d/block-nvidia` and installing `nvidia-driver-pinning-<ver>`, `nvidia-driver`, and `firmware-nvidia-gsp`. If the candidate does not match, the installation aborts cleanly.

On Debian 13 (Trixie) the official `cuda-keyring` package is used instead (`wget` + `dpkg -i`), since extrepo cannot configure the repo correctly on Trixie. After enabling, the script always runs an explicit `apt update`, then installs `nvidia-driver-pinning-<ver>` if available (official NVIDIA pinning, optional), and finally installs the unified metapackage `nvidia-open` plus `firmware-nvidia-gsp`. No manual pinning file is written; if `apt install` fails, the real apt error is shown and the installation aborts.
