- Theme is now class-based (.dark on <html>) with a System/Light/Dark toggle in
the sidebar, persisted to localStorage and applied pre-paint by an inline
script (no flash). Replaces the prefers-color-scheme-only behavior, so a phone
on a light OS theme can still choose dark and vice versa.
- New brand-derived --line token (Ink at 55%): a dark line on the light paper,
light on dark. The family-chart tree connectors had the library's default
white stroke and were invisible in light mode — now they use --line, as do
the pedigree brackets and the fan-chart sectors.
- Light/dark tokens use the exact brand palette (Ink/Muted flip; Bronze/Paper
constant).
Frontend only — no migration.

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.
