The SVG scaled to container width with height following the fixed
800×560 viewBox ratio — on wide windows the graph grew taller than the
viewport, the page got a scrollbar, and wheel-zoom scrolled along.
The graph page is now a flex column filling the main column; the canvas
takes the remaining height (flex: 1, min-height: 0), a ResizeObserver
feeds its measured size to ForceGraph as width/height, and the SVG
fills it exactly. LocalGraphPanel keeps its fixed defaults. Scope
deliberately layout-only (issue comment 1187): with no scrollbar there
is nothing for the wheel to scroll, so no non-passive listener needed.
The graph pack now asserts the main column does not overflow
vertically on the graph route.
