/* farm.lukealbertson.com
   A working tool, not a landing page. Read in a truck cab, in sunlight, on a phone.

   Design notes for whoever touches this next:
   - The display face IS the monospace face. This document's world is fixed-width USDA
     market news and scale tickets, so the numbers are the typography.
   - Two functional colours only: NET is green (money you keep), FREIGHT is rust (money
     the truck eats). Everything else is ink on paper. Colour is never decoration here.
   - The signature element is .bite: a shared price axis where a solid green bar ends at
     NET and a hatched rust bar runs on to the headline BID. Sorted by net, you can see
     a high far-away bid getting dragged behind a close one. That picture is the product.
   - No @import, no webfonts, no external anything. The page must load with the radio on
     and one bar of signal.
