tehran_taj/apps/user-app/src/views/HomeView.vue

<!--
  Redesigned home screen (replaces the previous port of legacy home/index.vue).

  Layout intent — shop first, account second:
    1. a slim brand bar with search + cart
    2. the live 18k rate strip (real: GET /pricing/latest)
    3. an editorial showcase hero built from real categories
    4. the category rail (real: derived from GET /catalog/products)
    5. "برگزیده" — a wide feature card + a two-column grid
    6. "تازه‌ها" — a horizontal rail
    7. the account block (real: GET /customers/:id when signed in)

  Data honesty, carried over from the previous version deliberately:
    - the API exposes no curated home payload, no promotions and no per-product
      price, so nothing on this page prints a rial price for a piece. Weight and
      making-charge percent are real per-variant fields; everything else shown
      is a label, not invented data.
    - categories come from the catalogue itself, so an empty catalogue renders
      an empty state instead of placeholder tiles.
