* - 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.
