/* =========================================================
   Workflow Orchestration — product page
   Self-contained by design: every page keeps its own stylesheet.
   The product-page foundation (type, sections, buttons, the
   product-UI kit, FAQ, related cards) is copied from the other
   product pages so they read as one system; blocks only this
   page uses are prefixed .wo-.
   Loaded after /index.css (palette, fonts, nav, footer, --u).
     --u  page layout and type
     --k  the inside of a product screen (= --u on desktop,
          fixed below 1180px)
