            // @subframe/sync-disable -- local fix: same hover lift as the inner sidebar (SidebarInside.NavItem) so both rails react identically.
            // @subframe/sync-disable -- local fix: deliberately without `will-change`. It pins the row to its own compositing layer for good, which drops the label from subpixel to greyscale antialiasing and leaves idle items looking faded or smudged. The browser builds that layer on its own while the scale animates. Same reasoning as the chat list rows.
            // @subframe/sync-disable -- local fix: `scale` is only a transitioned property while the row is lifted. The lift animates on the way up and drops the instant the pointer leaves, so a rail crossed quickly does not leave a trail of rows easing back down behind the cursor. The background keeps its fade in both directions.
