CSS Sonar Ping Ripple Animation

A military-grade sonar scope: conic-gradient sweep arm with a glowing edge, four concentric range-circle grids, four animated blips that appear as the sweep passes and each sprout their own CSS ripple ring. Data readout panels and a blinking status line. Share Tech Mono + Orbitron on phosphor-green #001408.
