/* ============================================================
   Builder · Phase 5 — Focus mode (Morpheus)
   Standalone prototype for moderne-ui#8531. Defaults to a
   ~2,000-step recipe. Groups collapse by default with total-step
   counts; the recipe list is windowed (only visible rows render)
   so it stays smooth at scale; a sticky "you are here" breadcrumb
   tracks the topmost visible row while scrolling. Sample data.
