/* ============================================================================
   Greybox footer — AMOLED black chrome with on-brand sticker art and a
   material-style Collections menu.

   Everything here is scoped to .gxf so it cannot touch the ct-/dl- footers on
   the contact and disclaimer pages. No Tailwind utilities are used: the build
   output (css/tailwind.min.css) is a purged subset, so new markup must ship
   with its own rules.

   Palette: brand gold (#d0a24f) plus three supporting accents used only as
   small art — coral, blue, mint. Backgrounds stay pure #000 (true AMOLED).
