/* Layout: a split hero sets the copy beside a live guilloché medallion; bands alternate between the bare ground
   and a raised one; a grid of products; one wide walkthrough of a payment; who it is built for; a grid of
   hallmarks; a routing bench; a developer split; contact; a quiet footer. Mint marks ForgeMint's own actions,
   brass marks money and the payment provider.

   Theme: the device decides. Dark is the default set of tokens; a device that prefers light gets the light set,
   and data-theme="light" or "dark" on <html> pins either. Every colour below comes from a token, so the two
   themes share one stylesheet. The code panel stays dark in both. */
