Problem

The delegate Row inside the peer ListView sets both:

anchors.fill: parent
anchors.verticalCenter: parent.verticalCenter

anchors.fill pins all four edges (top, bottom, left, right). Setting anchors.verticalCenter at the same time conflicts with the top/bottom bindings. QML emits a runtime warning and the resulting layout behavior is undefined.

Impact

The peer list delegate produces console warnings on every render and has unpredictable vertical positioning. One of the two conflicting anchor bindings must be removed.

## Problem The delegate `Row` inside the peer `ListView` sets both: ```qml anchors.fill: parent anchors.verticalCenter: parent.verticalCenter ``` `anchors.fill` pins all four edges (top, bottom, left, right). Setting `anchors.verticalCenter` at the same time conflicts with the top/bottom bindings. QML emits a runtime warning and the resulting layout behavior is undefined. ## Impact The peer list delegate produces console warnings on every render and has unpredictable vertical positioning.
