/**
 * ItemsAndSearchPanels manages the shared layout and state for:
 *   - ItemsPanel, which shows the items in the outfit now, and
 *   - SearchPanel, which helps you find new items to add.
 *
 * These panels don't share a _lot_ of concerns; they're mainly intertwined by
 * the fact that they share the SearchToolbar at the top!
 *
 * We try to keep the search concerns in the search components, by avoiding
 * letting any actual _logic_ live at the root here; and instead just
 * performing some wiring to help them interact with each other via simple
 * state and refs.
