Researched how FamilySearch/Geni/MyHeritage lay out trees (switchable pedigree/portrait/fan, an interactive canvas with pan/zoom + click-to-recenter, gender colors, birth-death years) and built a real Tree page on the MIT d3 library family-chart instead of a flat list. Ancestors + descendants around a focus person, click any card to recenter, drag to pan, scroll to zoom — scales to large imported trees. Tree is now the first per-tree sidebar item and the default when opening a tree; People keeps the searchable directory + add/edit.
