- Runtime window icon: X11 takes the embedded 512px PNG up front
(_NET_WM_ICON), Wayland resolves it from oak.desktop via the app id,
Windows reads it from the exe's icon resource.
- assets/appicon: 512px PNG + 7-size ICO rasterized from Oak_Icon.svg.
- Windows: oak.rc (ICON resource ID 1, also the Explorer icon) compiled
by build.rs through embed-resource.
- Linux packaging (deb/rpm/PKGBUILD/oak.spec): install Oak_Icon.svg
into the hicolor scalable theme alongside the existing 512px PNG.
- macOS: no change needed - cargo packager already builds the .icns
from the CD-generated icons/icon.png (same source art).
