The desktop AC8 test flaked in CI: it asserted replaceState was never
called after a tap, but the mount-time URL mirror fired late with the
unchanged default view (cx=0&cy=0&z=1), tripping the assertion. Assert on
the rendered viewBox instead — a pure function of the view state — so a
recentre shows as a shifted origin and a desktop tap leaves it identical,
with no dependence on the noisy mirror-effect timing.

Sara/Elicit noted AC8 was proven only as recentreAbove geometry, never as
wired behaviour. Add route-level tests that mock window.matchMedia: a tap
recentres the canvas (mirror effect re-fires) when the mobile breakpoint
matches, and leaves the view untouched on desktop where the side panel is a
flex sibling that never overlaps the canvas.

The shared parent-pair child loop read group.childIds[i] while iterating
the filtered childCenters, so a child without a position would desync the
id from the centre — and that index now also drives the active-connector
lookup. Ride the id on the mapped {id,x,y} centre so the two never drift;
a positionless child drops out of both together.

Sara/Elicit flagged that AC5 was proven only at the isConnectorActive
predicate level. Add render-layer assertions: no connector group carries a
dim opacity when nothing is selected, and selecting Vater dims exactly the
vertical feeding the collateral child Tante. Exercises the shared
parent-pair per-child <g opacity> wiring.

Bump DIMMED_OPACITY 0.4 -> 0.45 so dimmed outlines/labels stay legible
against bg-surface in both themes (dark mode dims already-light mint, the
riskier case). Import the constant into StammbaumTree.svelte.test.ts so the
node-opacity assertions track it instead of a hard-coded '0.4'.

Group opacity on the node <g> made the whole node translucent — including
its card fill — so the connector lines drawn beneath a dimmed node showed
through it. Render the card fill at full strength outside the dim group and
move the lineage focus+dim onto an inner content group (outline + labels)
only. The focus ring also leaves the dim group, so a dimmed-but-focused
node keeps a full-strength ring.

On a touch viewport (below the md breakpoint, where the bottom sheet
overlays the lower part of the canvas), tapping a person now auto-centres
them via recentreAbove with a 0.3 height bias, so the highlighted anchor
lands in the band above the sheet instead of behind it (AC8). On desktop
the side panel is a flex sibling that never covers the tree, so the bias
is 0 and selection does not pan. StammbaumTree's recentre effect takes a
centreBiasFraction prop and the page drives it from a matchMedia flag.

recentreAbove recentres on a node and lifts it above the viewBox centre
by a fraction of the zoomed viewBox height, measured against the
auto-zoomed height. On a phone this lands the tapped anchor in the band
above the bottom sheet instead of behind it (AC8). A zero bias is exactly
a legible recentre.

StammbaumTree derives the active set from the raw selectedId rune: the
adjacency index is built once per edge set ($derived on edges) and the
walk re-runs on selection change ($derived.by on selectedId). It passes
`dimmed` to each node and the isConnectorActive predicate to the
connectors. A null highlight (no selection) leaves everything full
strength, so an unselected tree never dims (AC1) and a ?focus deep link
paints already dimmed on load (AC9, selectedId seeded server-side).
Adds StammbaumTree.svelte.test.ts cases for AC1 (no dimming when
unselected), AC2 (bloodline + spouses full, collaterals dim), AC6
(re-select recomputes and clears the previous highlight), and AC7
(close returns the whole tree to full strength).

StammbaumConnectors gains an isConnectorActive(a, b) predicate prop and
wraps each logical connector in a <g opacity> group. A connector is full
strength only when both joined people are active; otherwise it dims to
DIMMED_OPACITY. The shared parent-pair drop+bar keys on both parents,
while each child vertical keys on both parents AND that child — so the
bar stays lit to a lineage child yet dims to a collateral sibling on the
same row. Defaults to always-active, so no highlight means no dimming.

StammbaumNode gains an optional `dimmed` prop that sets group-level
opacity (DIMMED_OPACITY) on the node's root <g>, so the box, accent bar,
name, and dates fade together as one unit. A lineage-fade CSS transition
eases the change and is neutralised under prefers-reduced-motion. The
selected-node styling (active fill + mint accent bar) is untouched.

Pure, DOM-free traversal over the family graph. Given the relationship
edges and a selected root, highlightLineage returns the active id set
(root + full pedigree upward + full descendant tree downward + every
spouse of those blood people, as active leaves) and a connector
predicate active only when both joined people are active.
The walk is guarded by the accumulating visited set, so cyclic PARENT_OF
data terminates (REQ-STAMMBAUM-04 / AC10). SIBLING_OF and social
relation types are ignored, so collaterals never enter the active set.
