+# ==========================================================
+# Description:
+# Shares a physical GPU (Intel iGPU, AMD or NVIDIA) with an
+# LXC container on Proxmox VE. Unlike VM passthrough, the
+# host keeps using the GPU — containers access it through
+# device nodes, not via VFIO binding.
+#
+# Features:
+#  - Multi-vendor detection (Intel / AMD / NVIDIA)
+#  - Multi-GPU selection via checklist
+#  - Switch Mode: detects GPU bound to vfio-pci (VM) and
+#    offers to free it before LXC passthrough
+#  - SR-IOV check (blocks unsupported configurations)
+#  - Automatic dev-node enumeration (DRI, KFD, NVIDIA)
+#  - GID alignment (video / render) between host and CT
+#  - Distro-aware driver install inside the container
+#    (Alpine / Arch / Debian-Ubuntu / NVIDIA .run fallback)
+#  - NVIDIA userspace version matched to host driver
+#  - Container memory bump during NVIDIA install (restored)
+#  - Optional GPU guard hookscript integration
+# ==========================================================
