Final corpus-graph PR. Connects the graph to the chair's workflow and rounds
out the Obsidian-grade interactions.
Backend (web/graph_api.py): neighborhood depth cap 2 → 3 (still bounded by
NODE_CAP_MAX).
Frontend:
- URL deep-link: /graph?focus=cl:<id> is read on mount and written on focus
change (router.replace, scroll:false). GraphView wrapped in <Suspense> per
Next 16's useSearchParams requirement.
- "הצג בגרף" button on the precedent detail page → /graph?focus=cl:<id>.
- Depth slider (1–3) in the focused overlay → useNodeNeighborhood(id, depth).
- Export PNG: grabs the rendered <canvas> from the area ref → toDataURL →
download; failures surface a toast (UI4).
- Rich node panel: precedent nodes fetch headnote/summary via the existing
usePrecedent hook (Skeleton while pending, error surfaced — UI4).
- Edge-type legend (ציטוט / נושא-תחום / יומון) added under the node legend.
Deferred (noted for a later pass): expand-in-place merge, search→camera-center.
web-ui build + lint pass. Invariants: G2 (depth change is read-only), UI4
(PNG + detail errors surfaced, not swallowed). api:types post-deploy.
