/* GuideMate Brain — "Analyze Me" dashboard.
 * Follows the site's control-panel-left / info-right convention: the shell,
 * navy control panel (lc-control), and cream reading pane (lc-display) all come
 * from learning-center.css. The pg-* donut / buckets / chips / heatmap / mistakes
 * classes come from there too. This file adds only the subject-scope pieces:
 * the single card wrapper, the IB-skill ladder, chapter rows, the mastery-band
 * legend, and the clickable-donut concept breakdown. */
