/* ==========================================================================
   taktek — studio identity
   --------------------------------------------------------------------------
   A rebuild, not a retheme. The old system was a card grid on a blueprint
   grid in cream and solder orange, which read as a product landing page for
   two apps. This is a studio index: paper, one signal colour, and the work
   in a numbered list where the type does the work instead of boxes.

   The signal green is the only colour on the page. It marks live things: the
   cursor in the wordmark, a link you are about to follow, the rule under a
   row you are hovering. Everything else is ink on paper.
