/*
  category.css
  BenQ Bangladesh — Product Category Page
  Dedicated stylesheet for pages/category.html only: page header,
  sidebar filters (category + price, with a mobile slide-in drawer),
  toolbar (result count, sort, grid/list view toggle), active-filter
  chips, product grid/list, empty state, and pagination.

  Depends on the design tokens in css/style.css and the
  .pf-product-card / .pf-btn / .pd-breadcrumb styles from
  css/components.css and css/product.css, which this page reuses
  for visual consistency with the rest of the site.
