Queue Pulse Lanes

queue-pulse-lanes

A queue/throughput background that renders your lanes rather than decorative streaks: pulses flow through restrained lanes, congestion makes them denser and slower, completed work fades into a tail history band, and blocked/delayed lanes carry a non-color stop cap + glyph. Density thins over a readable safe area. Deterministic (SSR-safe), light/dark, reduced-motion-static, forced-colors-safe, offscreen-paused. SVG + CSS only.
