 * Built-in palette keys used by bar/pie/line fills across the SimpleCharts family.

 * component's CVA (see `BarList/classes.ts`).
 *
 * `slate` is the neutral default and intentionally uses `bg-states-primary-pressed`
 * instead of a raw palette class so it inherits the row's interactive tinting.
