   PIT — layout and components.

   Every colour, font and spacing value comes from tokens.css. Nothing is
   hard-coded here.

   Design intent: a dense, sober analyst's tool. Numbers are right aligned with
   tabular figures, hierarchy is carried by type and rules rather than colour,
   gold appears sparingly as an accent.
