// widgetStatusBar.c  -- StatusBar widget
//
// A horizontal container that draws a sunken border around each visible
// child to create the classic segmented status bar appearance. Children
// are typically labels or other simple widgets, laid out by the generic
// horizontal box layout. The status bar itself has no special layout
// logic -- it's a standard HBox with tight padding/spacing and the
// extra per-child sunken border decorations.
//
// The border drawing is done as an overlay on top of children rather
// than as part of the child's own paint, because it wraps around
// the child's allocated area (extending 1px past each edge). This
// keeps the sunken-panel effect consistent regardless of the child
// widget type.
//
// No mouse/key handlers -- the status bar is purely display. Children
// that are interactive (e.g., a clickable label) handle their own events.
