   arcscan-enterprise.css — Visual hierarchy + component styles for the
   enterprise UX refactor. Loaded AFTER arcscan-design-system.css in
   base.html so atk-* tokens (colors, spacing, type scale) resolve.

   Adds:
     §1  Panel hierarchy (.atk-panel--primary | --secondary | --muted)
     §2  Action header (dashboard hero replacement)
     §3  Security Score hero ring
     §4  Risk card
     §5  Attack Path preview graph
     §6  Action button polish (extends atk-btn)
     §7  Severity badges
     §8  Launchpad (3-action variant)
     §9  Decision-cue helpers
