/**
 * Coach Profile Editor — Course Detail Split-Pane (Scene 3 redesign v3)
 *
 * Two-pane takeover view inside the editor. Left = bound levels,
 * right = gym library (planner-style cards via .lib-card visual classes).
 *
 * Reuses .lib-card / .lib-detail-* classes from coach-planner.css for
 * the right pane's card visuals + click-to-expand detail. Those rules
 * already exist on the planner page — duplicated here scoped under
 * .cp-course-detail-pane-right so the editor doesn't have to load the
 * full coach-planner.css.
