/* ============================================================================
   Ambry — site design system.
   Concept: "the grid instrument." Ambry is a data grid for databases, so the
   site is built as one: a precise, light, coordinate-labeled cell grid. Deep
   pine is the brand; amber marks only live/editable states, echoing the app's
   pending-change highlight. Deliberately unlike the dark/blue/glow house style.
