-// Disable GPU hardware acceleration globally for maximum stability across
-// all GPU configurations (no GPU, integrated, discrete).
-//
-// Rationale (following VS Code's philosophy):
-// - Page/file loading is async data fetching — zero GPU dependency.
-// - The original per-platform GPU branching was added to avoid CPU rendering
-//   competing with sync I/O on Windows, but all file I/O is now async
-//   (fs/promises), so that concern no longer applies.
-// - Software rendering is deterministic across all hardware; GPU compositing
-//   behaviour varies between vendors (Intel, AMD, NVIDIA, Apple Silicon) and
-//   driver versions, making it the #1 source of rendering bugs in Electron.
-//
-// Users who want GPU acceleration can pass `--enable-gpu` on the CLI or
-// set `"disable-hardware-acceleration": false` in the app config (future).
