/* ==========================================================================
   SivaTools — visual system
   "measured plaster on warm paper"

   Derived from the Steep reference system (serif analytics on warm paper):
   a near-monochrome editorial canvas, display serif held at weight 400,
   floating product artifacts, and colour rationed to a single warm accent.
   Two deliberate departures, both grounded in the product:

   1. The canvas is warm paper rather than white — SivaTools' existing
      identity, and the right ground for drawing-derived evidence.
   2. The accent is #e98b1e, sampled from the plaster material as Revit
      actually renders it in the screenshots on this page. The brand colour
      and the product output are the same colour by construction.

   Type is a three-register system: a display serif for voice, an
   engineering grotesque for interface, and a monospace for every number
   the product measures.
