/* Classroom Walkthrough — styles

 * Two layouts share this file. `.layout-walk` is the tablet screen: large
 * targets, lots of breathing room, nothing decorative. `.layout-admin` is the
 * ordinary desktop screens.
 *
 * Body text is 1.15rem (about 18px). Anything smaller is reserved for
 * genuinely secondary text — timestamps, meta lines, fine print.
