/* ===========================================================================
   SolutionsSales -- 画面イメージ (FRAGMENT:mock), part 3:
   AIエージェント chat: thread, work log, composer. Behaviour: sales-mock-3.js.
   - No JS (.sa-mock-demo not .is-live): the whole exchange shows.
   - Live: data-chat="idle" shows the greeting only, "run" adds the request +
     the work log, "done" adds the answer with its 3 suggestions.
   - Motion only under html.sa-motion, and only while a request plays
     (.is-play), so reopening the tab does not replay the exchange.
   Contrast: --muted on --sa-flat 4.93:1, on #FFF 5.48:1; --sa-acc-ink on
   --sa-tint 6.29:1; #FFF on --sa-acc 5.79:1; --ink on both tints > 12:1.
