/* ═══ Reading Hub — practice.html exam-style rendering ═══
   The .r-* rules below are copied verbatim from css/practice.css (the practice
   portal's Inspera-style reading renderer) so the Reading Hub renders passages +
   questions with identical look. Class names do NOT collide with the hub's own
   .q-* classes, and every design token used here (--acc, --bg, --text, --gold,
   --green, --red2, --border2, …) is already defined by the hub's body.dark /
   body.light blocks — so this stylesheet needs no token layer and themes for free.
   Keep in sync with practice.css if the practice renderer's styles change. */
