The CMake target stays 'uploader' but the output binary is now 'photog',
matching the package and app, so 'nix run' and the desktop entry resolve
it (nix run looked for bin/photog and failed on bin/uploader). Also set
meta.mainProgram.
- Web: favicon.ico + png icons under static/, served from the site root
and linked from every page head.
- Android: the artwork becomes the launcher icon — the 432px adaptive
foreground over the gruvbox background, replacing the placeholder vector
drawables.
- Desktop: the icon is the Qt window/taskbar icon (embedded via app.qrc),
and the app is now an installable package — a wrapped binary, a
photog.desktop entry, and hicolor icons — so `nix profile install
./desktop` puts "Photog" in the application menu.
