/* AIの書斎（/ai-consulting）と、AIの見本3ページ（/ai-sample-rules・/ai-sample-curriculum・/ai-sample-estimate）だけの見た目。
   ・共通の部品と色の変数は yakata.css（--yk-*）。ここのクラスは ys-（書斎）で始める（共通の yk- とぶつからないように）。
   ・夜の区画（入口・机・本棚・出口）は yakata.css の .yk-shosai。ほかの区画は、冷たい紙の上（.ys-kan）。
   ・動きの初期状態は、JSが付けたクラス（.is-game・.is-ugoku・.is-tabu など）の下にだけ書く。
     JSが無い・動きを減らす設定のときは、机の上の見本も含めて、すべて静的に読める。
   ・印刷：見本のページは紙（.ys-sheet）だけ。書斎のページは、相談メモだけの印刷（html[data-insatsu="memo"]）と、ふだんの印刷。 */
