The engine draws the lane after the gauge, and the lane's black top edge (y 276) hid the cells' last six rows; the cabinet's gauge sits over it (cells down to y 281). The gauge leaves a redraw (g_dan_gauge_redraw) that the dan background's draw_fore repeats, clipped to that strip (y 276-288). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
