/* ============================================================
   Zeroth — site shell styles (light "commissioning document" system)
   Used by the marketing pages: index, services, system, work,
   team, contact, privacy, terms.

   The firm is paper; the system is dark glass. Light engineered-
   document surfaces carry the words; the running OS appears only
   inside contained dark panels (.panel-sys) and the footer. The
   brand mark keeps its exact colours (pulse #3DF5A6 ring, lime
   #D4FF4A dot) and sits on a small dark tile so it always reads
   against paper.

   shared.css remains the stylesheet for the product/utility pages
   (approve, connected, unsubscribe, campaign template) and must
   not be edited as part of the marketing redesign.
