// PmFolderChip — the LIST-mode folder cell (PlaylistManagerView.slint:380-466).
// 52 px tall, r8, elevated → surface-hover, 0.6 opacity while hidden. The mount
// forces `width: 184` (`:1382`) so every cell in the wrapping grid has the same
// pitch; the component's own intrinsic width is never used.
//
// The body enters the folder; only the pencil opens the folder editor.
//
// Two hover-revealed children — the count and the pencil — at opacity 0/1 with
// the reference's 150 ms fade. OPACITY, not visibility: the count keeps its
// layout slot at all times (the same trap qml/shell/Sidebar.qml:996-1008
// documents). Hover is the reference's OR over the chip's and the pencil's own
// areas (`:437`), because the pencil's MouseArea sits above the chip's and would
// otherwise steal `containsMouse` from under the pointer.
//
// LAYOUT DEVIATION, stated: the reference is a `HorizontalLayout` whose
// children are content-sized inside a container the mount widens to 184, so
// Slint distributes the slack through the wrapper layouts. QML has no
// equivalent distribution here, so the icon + name + count are content-packed
// from the left gutter and the pencil is pinned to the right gutter — which is
// where a 24 px hover affordance belongs in a fixed-pitch chip. Every metric
// (12/12 padding, spacing 8, icon 36/glyph 20/r8, name 13/500 capped at 120 and
// elided, count 11) is the reference's.
