/* ==========================================================================
   Inventory Center IA V2 — 三層式資訊架構重整 (庫存管理中心 → 5 個第二層
   中心 → 第三層功能卡片 → 既有工作頁). Pure frontend navigation/landing-page
   layer: InventoryCenterMap.js (taxonomy) + components/CenterCard.js +
   components/CenterLandingFactory.js + InventoryShell.js (breadcrumb +
   2-tier sidebar). No backend, no API, no change to any existing work-page
   file's own CSS — every class below is self-contained under an "ic-"
   prefix (breadcrumb bar uses "inv-breadcrumb-" to match InventoryShell.js).
   Reuses shared Foundation classes untouched (.inventory-page-header,
   .inventory-page-title/-subtitle, .prototype-banner, .inventory-section-card,
   .item-tab-note, .inventory-btn-*, .status-badge, .inventory-badge-*,
   .inventory-empty-state).
   ========================================================================== *//* ---- Breadcrumb bar (section 十一): persists inside #content-area as a
   sibling above #content-page-root; InventoryShell.js keeps it intact even
   if a page bypasses the Shell and replaces #content-area directly (see
   ensureShellStructure in InventoryShell.js) — self-healing on next
   navigateTo(). Height fixed at 28-32px per spec. ---- */#inventoryHostRoot .inv-breadcrumb-bar {

   breadcrumb bar above #content-page-root shrinks the space actually
   available to them by its own height — this compound-selector override
