Re-setting el.className each render dropped the maplibregl-marker class
(position:absolute), so live markers fell into document flow and stacked
+32px each — vehicles drifted south, worse when zoomed out, dragging their
plate labels with them. Use classList (preserve maplibregl-marker) and wrap
pin+plate in a .veh-inner positioning context so a class change can't reflow.
Verified: every marker now projects to dX=0,dY=0 on its coordinate.
