Full light/dark theme toggle; brand-aware connector lines

- 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.
