// The app-wide selection checkbox (LocalLibraryView.slint:486-515): a 13px
// circle, accent-filled when on, 1.5px muted ring when off, 8px white check
// glyph — or a minus glyph for the folder tri-state "partial".
//
// Slint declares this inline inside TreeRow; the Qt port also needs it on
// the album cards and the track rows in multi-select, so it is its own file
// (three call sites, one shape).
//
// `toggled` carries the click's modifiers: this disc IS a select-mode click
// target, and one that dropped them turned every Shift-click on it into a
// plain toggle (controls/SelectionModel.qml).
