/* scope.css · the BOUNDARY page for the Halcyon candidate branch.
   ============================================================
   The boundary is the sharing rule: a status and a short summary can be
   shared, and every controlled file stays protected. This page makes that one
   rule legible with the live node-graph map on the left (proof-map.js, fed the
   real six-department dataset and styled by proof-map.css) and two plain
   columns (Can be shared / Stays protected) on the right.

   The map sits on a focused dark "viewer" panel (.scope-map-canvas reuses
   .analysis-stage from halcyon.css) so the node-graph engine, which is tuned for
   a dark ground, reads cleanly whether the page theme is light or dark. Every
   color here is a Datum token, so theme.js flips light/dark for free. Text
   always sits in its own panel, never over the map art.

   Legibility: AA on the ground color, readable measure, no horizontal overflow
   at 1280px or 375px (minmax(0,1fr) tracks, min-width:0 content cols).

   MOTION CONTRACT: motion is OFF by default. Inside
   @media (prefers-reduced-motion:no-preference) the .settle elements rise into
   place via a self-completing CSS animation, so the reveal never depends on a
   JS observer firing (the right column is always readable). motion.js may still
   add .in for its own bookkeeping; the animation does not need it. Reduced
   motion shows the full page instantly, fully readable, no movement.
