A fresh visit (no URL state) now opens at INITIAL_VIEW (z=3) so node tiles and
generation labels are legible on arrival; the fit-to-screen control still zooms
out to the whole tree (DEFAULT_VIEW, z=1). Shared links with ?z still win.

The server load parses and sanitises the shareable pan/zoom params (degrading
Infinity/NaN, clamping zoom) into initialView, which seeds the page view. A
crafted link can no longer blank the SVG (Nora). US-PANEL-002 AC2 groundwork.

- /stammbaum/+page.server.ts loads GET /api/network (already filtered
to family members on the backend) and returns nodes + edges.
- +page.svelte holds the page shell, manages selectedId (with
?focus={id} deep-link support) and zoom state, renders the empty
state when nodes.length === 0 (icon + heading + body + link to
/persons), or the tree + side panel otherwise.
- StammbaumTree.svelte: BFS-based generation assignment from roots,
spouses promoted to the deeper generation so couples sit on the same
row, alphabetical sort within row, simple grid layout. SVG nodes are
role="button" + aria-label="{name}, {birth}–{death}" +
aria-expanded={selected}, with click + Enter/Space activation. Solid
parent→child connectors; mint spouse line with midpoint circle, dashed
if SPOUSE_OF.toYear is set (former spouse). Zoom maps to viewBox.
- StammbaumSidePanel.svelte: lazily loads
/api/persons/{id}/relationships and /inferred-relationships when the
selection changes; shows direct chips (mint), top-5 derived chips
(grey), and a "Zur Personenseite →" link. Escape closes the panel.
