-- **Steamify wizard pages in the installer**, before anything is installed:
-  the same choices as Steamify's menu (conversion, boot into gamescope or
-  desktop, theme, Deck icons, single user, shortcut + non-Steam game,
-  notifications, VRAM booster, HDMI-CEC, Steam Machine support + power-off
-  fix), defaults ticked like a first run. A Calamares page (netinstall-style
-  YAML or a QML module in the `show` sequence) stores the ticked ids in
-  global storage; `steamify-install` passes them to
-  `steamify.sh --backend apply <ids>` (`--boot gamescope|desktop`) instead of
-  `--defaults`.
+- **Checkboxes instead of the leave-out list**: Calamares has no ready
+  checkbox page whose ticks come out as plain ids (netinstall's are package
+  installs); it would take a QML page (packagechooserq) or a small C++
+  module. Steamify's side (`--skip`, `--boot`) stays the same.
 - **Branding**: the live session's os-release says "Steamify, based on
   CachyOS" (Hello's subtitle); Hello's window title and the boot menu still
   say CachyOS. Check with the CachyOS team.
