/* SLE-TH-detail-pane — full-viewport slide-in detail overlay.
 *
 * Shape: fixed-position overlay with sticky header + scrollable body +
 * sticky footer. Animates in from the right.
 *
 * Use cases (intended): activity editors, item detail views, bill review
 * panes. Apps with pre-existing variants (campscout `.panel-*`) can adopt
 * progressively — the primitive doesn't auto-replace them because the
 * existing variants may differ on position (absolute vs fixed), visibility
 * toggling, and animation curve.
 *
 * Children:
 *   .suite-detail-pane-header — sticky top, title + close
 *   .suite-detail-pane-body   — scrollable content area
 *   .suite-detail-pane-footer — sticky bottom action bar (optional)
 *
 * Depends on tokens.css.
