/* Threefold Capital: the Financial Intelligence Studio (/calculators).

   Loaded only on the Studio's pages, after site.css, whose colours, type and square corners it
   uses. The working page is an analyst's sheet: assumptions in a column on the left, the figures
   they produce on the right, and the schedules, scenarios and downloads underneath. Rules are
   thin and corners square, as everywhere on the site; gold marks what can be acted on and the
   figures that matter most. */
