look on path:NN centers the target line in the pane body (scroll = line - body/2, clamped at 0): fresh opens lay out first (computeGeom after placeDoc) to center with the real body height; dedup re-looks recenter the existing pane. look-file golden shifts accordingly; new look-center snap proves fresh-open centering, dedup recentering, and the top clamp.
