   The landing page — the only screen in this product with no work to do.

   Everywhere else, layout serves a biller who is holding a trolley queue. Here
   the reader has time, so the page is allowed depth: a dark teal hero, the
   product's own bill rendered beside it, and real figures counted out of the
   database underneath. It is still not decoration for its own sake — every
   section answers "what is this and can I try it".
