/* ================================================================
   HOME.CSS — the Learner Home.

   1. The onboarding course question (#page-course-pick,
      practice/course-pick.js). It borrowed the retired placement set-up's
      tiles (2026-09-26) and keeps their `placement-*` class names.
   2. The idle card: one screen, two columns (Seth, 2026-09-26: "simplify
      it to fit onto a single page"). Measured learning, the multiplier and
      the Continue button on the left (styles/xp-panel.css styles what
      practice/xp-panel.js paints into it); daily XP above knowledge toward
      the course on the right.
