/* ==========================================================================
   Alia Exchange Office — public rate board

   One rule drives this layout: the NUMBERS are the product. They get the
   space, the weight and the contrast. Everything else is a label.
   Rows divide the screen height evenly, so the board always fills the
   display exactly — no scrolling, no dead space at the bottom.
