/**
 * Section bounds on the active canvas — the union of explicit section
 * rectangles and member frame bboxes. Empty sections are included so a frame
 * can still be dropped onto one.
 *
 * A frame's box is measured to `resolveFrameHeight`, which is the frame
 * itself; the rendered label is an overlay above it. Do not widen these bounds
 * to match the label: they decide which section a dropped frame
 * joins, the search takes the first section it intersects, and lanes sit 210
 * apart while sections sit 120 plus the header reserve — so a taller box
 * would start overlapping its neighbour and reassign frames to the wrong
 * section. Understating is the safe direction, and nothing is drawn from
 * these bounds any more that a designer could see the shortfall in.
