/* Ask GoSEQ, answered as an itinerary (js/askflow.js): a full-screen sheet in the style of Find my stop and the live
   trip moments. Small-caps kicker, the question in big type (its parts tappable), steps that tick, a skeleton, then the
   answer: when to leave, huge, over a timeline. Follows the app's light and dark themes. Motion: the sheet rising, the
   ticks, the answer arriving (opacity and transform only); reduced motion keeps only fades. */
