 * `#app > section`) is exactly the 1800x960 usable area the spec calls
 * "x 60-1860, y 60-1020" — so a spec position like "x:60,y:250" becomes
 * "left:0,top:190" below. Absolutely positioned children measure offsets
 * from the section's padding edge, which sits at the section's own outer
 * edge regardless of the section's own padding, so no padding override is
 * needed here. */
