/* ==========================================================================
   Evidence Scan - the RADAR (experimental, scan-beam copy).
   A fixed full-viewport layer behind the hero -> problem -> question arc:
   the hidden CVE print (two lagged microtext sheets) plus the radar-scope
   furniture (range rings, crosshair, ticks), all silver-locked foil - the
   cursor never excites them, ONLY the sweep lights them. The WRAPPER
   carries a conic phosphor-wedge mask: a sharp bright leading edge with a
   long decaying tail (the CRT afterglow), rotating about the radar centre.
   beam.js owns the rotation (slow idle spin, scroll accelerates) and the
   find choreography (blip ping -> FIRE list pill, styles in firelist.css).
   The foil canvases are never resized/hidden individually (wrapper-level
   masking only). Remove the layer div + beam.* + firelist.* to kill the
   experiment.
