+The day-cycle paper outline is one of those scene SVGs (#582). Its root CSS box
+is stage-sized and owns the triple drop-shadow and idle `will-change: filter`;
+its child is only an exact paper alpha silhouette. During a gesture the same

 Neither the attribute nor an equal style property is written when its value is
 unchanged: an idle frame must leave the DOM byte-identical, or the settled raster
 shifts by a few colour levels and golden frames flap. `commitHouseplanViewport`
