 | Owns .raas-problem__* (head, three problem cards, transition) and the
 | shared .raas-problem-flow chip track used for AD -> REVENUE.
 |
 | journey.js adds .is-armed to [data-raas-flow] and .is-lit to the
 | children marked [data-raas-step] as they scroll into view, so chips
 | highlight in order.  Nothing is dimmed or animated unless that script
 | runs and the user allows motion — a static render shows every chip.
