/* ---------------------------------------------------------------------------
   Rolou Barato

   The page has exactly one job: let someone scan down a column of R$/kg and
   find the cheap row. The chrome stays out of the way of that, but it's
   allowed a little personality -- rounder shapes, and colour drawn from the
   real filament palette (see the wordmark thread) rather than pure monochrome.
   The R$/kg figure is still the one loud element; now it's a loud colour too.
