/* ============================================================================
   X-ray mode (community#39) — L2 system panel, L1 inspector drawer, the
   per-message head chips, and the event DAG. The visible toggle is the
   header's .xrayButton (Header.css); this file styles only x-ray's own
   surfaces. Consumes the design-system tokens in index.css exclusively, so
   light/dark theming is automatic. Restrained blueprint cues only: dashed
   borders and a faint dotted grid on the DAG canvas — the app must stay a
   usable app while x-ray is on.
