Third-party files in DroidDeck's Ubuntu runtime (tools/ubuntu/overlay):

- Vapor (color scheme, Plasma theme, look-and-feel package, Konsole profile and color scheme) and the
  steamdeck-gaming-return / distributor-logo-steamdeck icons: Valve's steamdeck-kde-presets
  (https://github.com/Jovian-Experiments/steamdeck-kde-presets), GPL-2.0-or-later (look-and-feel)
  and GPL-3.0 (Plasma theme), as their metadata states. The look-and-feel package's defaults, setup
  scripts and layout were adapted for DroidDeck; its Plasma 5 splash screen was left out.
- steam.svg: Papirus icon theme (https://github.com/PapirusDevelopmentTeam/papirus-icon-theme),
  GPL-3.0.

- KWin (kwin-wayland and related packages, version +droiddeck): Kubuntu's KWin source package,
  GPL-2.0-or-later, rebuilt with tools/ubuntu/patches/kwin. Corresponding source: `apt source kwin`
  plus those patches (https://github.com/Droid-Deck/DroidDeck/tree/main/tools/ubuntu/patches/kwin).
- Mesa (packages with version +droiddeck): Ubuntu's Mesa source package, MIT and others, rebuilt with
  the freedreno KGSL kernel interface enabled (tools/ubuntu/build-debs.sh). Corresponding source:
  `apt source mesa`.

Everything else in the runtime is Ubuntu's own packages, under their own licenses
(/usr/share/doc/*/copyright).
