/**
 * detail.summary — the header summary band (plan UI 3.2).
 *
 * A card above the tabs/sections: big title value, status Badge, up to 4
 * label/value meta pairs. Values go through renderReadValueExpr (same pills /
 * FK labels / date formatting as the body). The uiDesign.detail.summary
 * overlay wins key-by-key; unknown field keys warn + drop. Absent → no band.
