Three sliders behind a gear in the search panel (user-decided
2026-09-13), persisted per browser in localStorage with clamped
sanitizing on load. Default node size dropped 8 → 6 for dense graphs.
Mechanics: the mount effect is split — the data effect builds the
graphology graph + one frozen forceAtlas2 pass per snapshot; the render
effect mounts sigma and re-runs on settings change only. Sizes are
stamped onto the same graph instance (layout never recomputed), and the
arrowhead program is constructed per rebuild with ratios solved from
the settings (head px = thickness × lengthToThicknessRatio × 2; wideness
keeps the stock 0.8 shape). The camera position carries across rebuilds
via a ref, so a slider tweak never re-fits or re-lays-out the view;
useDeferredValue smooths slider drags.
Live-verified in the browser: sliders persist to localStorage, the
renderer rebuilds with zero console errors, hover/picking survives the
rebuild, and a zoomed-out camera stays zoomed out across a settings
change (labels-gate opacity as the observable). 355/355 tests,
typecheck, lint, build green.
