/**
 * SidebarPlaceholder
 *
 * Why we reserve a sidebar area even for branch users:
 * - Admin/dev will later need a branch selector.
 * - Branch users can still benefit from navigation and filters:
 *   - quick jump (year/month/day)
 *   - search filters (archive toggle, date range)
 *   - recent/favorites
 *
 * RHL-019:
 * - Placeholder only (no logic yet).
 *
 * Test/runtime note:
 * - See AppShell.jsx for details why we import React explicitly.
