Radar
See a signal as a glowing PHASE PORTRAIT on a radar — a van der Pol style 'oscilloscope in space': the waveform plotted against a short-delayed copy of itself (the (x, velocity) plane), so a pure tone draws a clean ELLIPSE, harmonics a ROSETTE, a relaxation/synth osc a characteristic limit-cycle loop, and noise a fuzzy cloud. A phosphor afterglow trails the trajectory like a real scope. An ANALYTICAL pass-through: wire a source (or a whole chain — but it reads best straight off an oscillator) into its input and its output onward, and the audio flows through UNTOUCHED — a zero-latency side-tap. An Analysis-family node (a visual signal indicator). The phase-portrait embedding lives in the kernel (chroma::phase_portrait); audio.js only taps the raw samples it owns and renders the radar.
