/* リッチ回答 (rich-blocks.js): charts, comparison cards, steps, timelines, diagrams and small tools inside an answer.
   Uses the AI アシスタント tokens of gpt.css (light and dark). Chart colours: the data-viz reference palette, both
   modes validated for colour blindness against this page's surfaces (#fff / #212121); light slots 3–5 sit below 3:1,
   which the table view (データを表示) and the legend make up for. Text never wears a series colour. */
