/* Groundline design system — dark-first.
   The visual language is a modern instrument panel over survey ink: deep
   charcoal surfaces, one luminous violet accent, hairline borders, and tables
   meant to be read. Every colour still has a semantic job; the glow is
   reserved for the few things that deserve attention (CTAs, the accent phrase,
   the value a metric exists to show). The site map keeps a light "plan sheet"
   background because survey linework is drawn in ink and must stay legible. */
