Stacked area chart with dashed strokes

<!--
  Замена библиотеки: см. c-chart-13.vue / docs/PORTING.md §19/§27.
  `stacked` даёт сложение областей, но `AreaChart` не поддерживает
  индивидуальные `strokeDasharray`/`strokeWidth` per-category — толщина и
  пунктир линий из оригинала (0.8/2px, сплошная/пунктир) не переносятся.
