How this works — Pedigree chart

A multi-generation family tree, built by recursively walking each animal’s sire and dam links.

clubcore_pedigree_tree() recurses through the _cc_sire and _cc_dam links to a chosen depth, producing a nested array. A second recursive function turns that into nested <div>s, and flexbox lays them out as the familiar left-to-right pedigree grid — no tables, so it reflows on mobile and prints cleanly via a @media print block.
