D10 returns every icon to D1's white tile, D8's dark one undone, the
gradients as D5 gives them (cobalt holds about 5.7 : 1 against white).
D9 adds the variants the systems colour by their theme, all from the same
glyph at the same place, drawn by tool/app_icons.py and written into the
projects by flutter_launcher_icons: Android's monochrome layer, which
themed icons tint (Android 13 and later), and iOS's dark and tinted icons
(iOS 18 and later), the dark one keeping D8's lift of 30 % towards white
on iOS's own dark background. macOS needs an Icon Composer file made on a
Mac and keeps the plain icon until then.
Whats-New: The app's icon is white again, and takes the system's colours where Android or iOS themes its icons.
Whats-New-De: Das App-Symbol ist wieder weiß und nimmt die Farben des Systems an, wo Android oder iOS seine Symbole einfärbt.
