The frame. A rounded screen border, the desktop’s signature chrome.
Popouts melt into it instead of floating on top.
The pill. A morphing bar at the top of the screen, and its popouts. It
is the centerpiece of the desktop; everything you summon (notifications, the
GNOME keyring prompt, the update island) grows from it.
The wallpaper, with the clock and weather desktop widgets painted on it.
No windows yet. Hyprland is a tiling compositor, so nothing is open
until you open it.
Mod is Super (the Windows or Cmd key on most keyboards).
