/**
 * Recovers each artboard's component tree from the flat core-object stream.
 *
 * Two facts do the work. An artboard opens a numbering space in which it is index 0 and the
 * components that follow it in the stream are 1, 2, 3…; and a component states its parent as an
 * index into that space. Both were settled against real files rather than assumed: across 127
 * artboards, numbering the artboard as 0 resolves every stated parent with no cycle and exactly one
 * root, while starting at the first component instead leaves 94 references out of range and 33
 * cycles.
 *
 * A parent that cannot be resolved is reported and the component becomes a root, so one bad
 * reference costs its own placement rather than the whole artboard.
