/* ============================================================
 * v5.0 — Selected-state for .radio-item via :has(:checked).
 * Pure CSS, no JS. Applies to Clinical Rotation, EOR (now single-
 * select), PANCE Body Systems (now single-select), and the Goal
 * Selection radio group itself — anywhere .radio-item wraps a
 * checked radio, the card lights up in success green to match
 * the tile pattern used by the Number of Questions group.
 *
 * SOP-CSS:
 *   - Tokens via var(--…).
 *   - No !important.
 *   - No JS.
 *   - Mobile-first (existing card padding already 14px → 10px @ <768px).
