/* AnonyLabs — Products (products.html only, owner 2026-10-13: "more like products", every product presented alike).
   Loaded after site.css; uses its tokens (--fg, --rule, --ease, --pad-*, …) and its catalogue index (.index).

   Every product is one <article class="product"> with the same parts, in this order:
     1. the file header (.dossier): file line + state, mark, name, definition, abstract, facts, the way in;
     2. the plate (.plate): the specimen figure (sticky) and its walkthrough (.walk), five steps.
   The figure is drawn in the product's colour (--accent); so are the active step's rule and number, the "Live"
   square, the open link's corner and the product strip's progress line. */
