/* =========================================================
   QUIZ PAGE — REDESIGN
   Same class names the JS already targets (.quiz-container,
   .quiz-timer, .quiz-progress, .quiz-card, .option-btn,
   .quiz-actions, #prevBtn/#nextBtn/#finishBtn) plus a handful
   of new ones for the top bar / progress bar / option cards.
   No IDs were renamed, so timer, navigation, and scoring JS
   need zero changes.
========================================================= */

/* .quiz-container used to be transparent — just padding, no
   background — so the timer/progress row floated directly on
   whatever the page background happens to be, with nothing tying
   it visually to the question card below it. Giving it the same
   soft-panel treatment as .practice-card (lavender surface, thin
   border) makes it read as one contained unit, and lets the white
   .quiz-card pop as the actual focal point inside it — same
   panel-vs-card relationship Practice Arena uses. */

/* Mobile "Questions" toggle — was a plain gray-outlined button
   sitting inline above the question card. Two problems: (1) it
   looked like ambient label text, not something tappable, and
   (2) once someone scrolled down into a long question, it
   scrolled out of view with nothing to bring it back — that's
   most of why it wasn't getting clicked. Fixed as a floating
   pill, pinned to the viewport so it's reachable at any scroll
   position, filled in the same purple used for every other
   primary action, with a live "answered so far" count so it
   reads as a real control instead of a label. */
