   12 · Showcase — layout
   Promotes concept 37 to the Sandvik design system. Image-forward catalog rows:
   a large product image anchors each item (recognise the tool by shape), with
   metadata, supplier/grade tags and stock + actions beside it. Each row is an
   sds-card; tags are sds-tag; actions are sds-button (primary CTA = the single
   electric-blue accent). Rail · command bar · 2-pane body (facets → catalog) ·
   status bar. Layout only; all color/space/type from --sds-* tokens. Shared
   vocabulary (.st, .num, review-bar) lives in ../_shared/base.css.
