/**
 * `<CartesianGrid horizontalCoordinatesGenerator>` that emits one grid line
 * per Y-axis tick.
 *
 * The recharts v3 default skips some ticks (notably the second-from-top) and
 * folds the topmost grid line onto the plot's top edge instead of placing it
 * at the topmost tick. That breaks the one-line-per-label visual contract:
 * a label can appear with no corresponding grid line.
 *
 * Using `yAxis.niceTicks ?? yAxis.ticks` and mapping each through the axis
 * scale produces a grid line at every rendered tick value. `dropEdgeGridLines`
 * then handles top/bottom culling against the resulting coordinates.
