   ------------------------------------------------------------
   Brief, from the brand guidelines:
   "Iron and lime. Near-black does the structural work.
    Lime fires once, on the thing that matters."

   MATERIAL MODEL — three deliberate layers:
     0  Iron canvas + a soft atmosphere field at the top of the
        page. The field exists so glass has something to refract;
        glass over flat black is just a grey box.
     1  Flat structure — hairline grids, rules, type. Most of the
        page lives here. Nothing frosted.
     2  Glass, reserved for elements that genuinely float above
        content: the header, panes over the atmosphere, and cards
        overlaying media. Frosting everything is what makes
        glassmorphism look dated; rationing it is what makes it
        read as a material.
