 * Bar chart renderer (vertical, grouped or stacked).
 *
 * Layout (chart-recipes.md → Bar):
 *   - Y axis: Nice Numbers from data range, always includes zero
 *   - Bar slot width: plotWidth / categoryCount
 *   - Bar fill width within slot: 70% (gap = 30% of slot)
 *   - Grouped: split slot among series (no extra gap inside group)
 *   - Stacked: cumulative y per category, topmost segment carries the slot
