/*
 * PickList / TransferList — Material UI "Transfer List" faithful styling.
 *
 * Self-contained, BEM-like, themed via CSS custom properties (the toggle.css
 * pattern). The component sets `--rr-picklist-accent` / `--rr-picklist-elevation`
 * / `--rr-picklist-radius` inline; everything below reads those vars so a single
 * accent/elevation/radius knob restyles the whole control.
