/* Ratchet Atlas — cartographic intelligence-console chrome around the D3 viewport.
   Shared /tech design-system tokens scoped to .atlas-doc (same convention as
   revolving-door / ai-abuse-registry). The force graph is the hero; the chrome is
   a map plate: graticule ground, tick ruler on the top edge, a margin band at the
   frame's foot carrying the key + live survey readout, and a dossier panel.
   Semantic accents: RED = money (funding edges, funding toggle);
   AMBER = cohort annotation (cluster hulls, cluster chips, method-receipt tags).
   Node/hull/link classes are painted by atlas.js — style only, never rename.
   Motion budget: the tech-kit LED blink is the one motion moment; everything else
   is hover/dim transitions only, killed under reduced-motion. */
