/*
 * Workspace chrome — split, fixture bar, panel edge.
 *
 * The footer `.workspace-bars` is a fixture, not a panel. It
 * sits outside the resize frame: status channel, then a
 * locked 50 / 50 control deck. Dragging the split only
 * resizes the panels above. The static divider stays at
 * center and is not the resize handle. Panel frames and
 * both dividers use `--workspace-edge`.
