Windows-native screensaver shipped as a .scr installed into
System32 via MSI. Built on Rust + wgpu with an HDR
Rgba16Float render pipeline, mip-chain bloom, ACES tone map, and a
configurable overlay pack. The egui settings dialog (the /c
screensaver verb) exposes admin-panel knobs for HDR, bloom, and overlay
dwell-time. GitHub-Releases-based in-app self-update.
Linux and macOS hosts build and run headless; native screensaver integration on those platforms is TBD.
