Two gaps from review of the public surface: - The public tree page showed only a list of names. Add the family-chart hourglass (PublicTreeChart) above the directory — the same renderer the member tree view uses, including the cycle-sanitisation that guards against a bad graph, fed by redacted public data. Click a card to recenter; "Open" links to the person's public page. Centers on the tree's home person. - The homepage had no path to /explore. Add an "Explore" nav link and an "Explore public trees" hero button. tsc clean; next build passes.
