+// Linux fix: Electron 43 (Chromium) defaults to a Vulkan graphics backend
+// that is incompatible with the Wayland ozone platform, and its GTK4 renderer
+// paints white on many Arch-based distros (CachyOS in particular). Both fail
+// modes cascade into the network service crashing and a permanent white
+// screen. Let Ozone auto-pick the platform, disable the Vulkan backend, force
+// GTK3, and drop the GPU-process sandbox (the zygote GPU child in AppImage
+// squashfs mounts doesn't inherit Wayland flags, which cascades into the net
+// service dying ~20s after launch). Must run before app is ready. Renderer
+// sandbox stays on — this only opens the GPU process.
+// See: electron/electron#33690 (GTK4), electron/electron#50462 (GPU zygote).
