// The quick pill: an Arc/clui-style floating command pill on a global hotkey, with the slime as its
// idle skin. macOS NSPanel semantics via type:'panel' (nonactivating), so the pill takes KEYBOARD
// focus while the app the user was in STAYS frontmost; no dock bounce, no space switch. The panel is
// created hidden at enable time so hotkey-to-visible is a show(), not a window boot.
