Root cause (diagnosed live on an N1X WoA box, confirmed by on-screen checks):
the Windows shell's sandboxed icon-extraction broker cannot read a standalone
.ico stored under %LOCALAPPDATA% (it gets a redirected/virtualized view), so
the Desktop + Start Menu shortcuts render BLANK -- regardless of icon format
(BMP vs PNG frames), ACLs, icon cache, or shortcut-creation method, all of
which were ruled out. The IDENTICAL .ico renders correctly from a path under
the user profile. Fix: write unsloth.ico to %USERPROFILE%\.unsloth instead of
%LOCALAPPDATA%\Unsloth (shim/launcher stay in %LOCALAPPDATA%). uninstall.ps1
removes the icon at the new location. Also drops the speculative SHGetFileInfo
"image-list prime" block added while chasing the wrong (format/cache) theory.
