    render-left-side: "Pure waveform and spectrogram: AI_inferred_frequency_plot, harmonic series bars, formant peaks, ADSR envelope curve, phase vectors, all in luminous oscilloscope green on black, labelled with musical/physics notation.";
    render-center: "The transition through the air: rarefaction/compression visualization, Chladni patterns on a plate, finite-difference simulation grids showing wave propagation, Doppler shift cones.";
    render-right-side: "Photoreal physical source: bow on string rosin dust in light, vocal cords stroboscopy, bat mouth open, jet nozzle shock diamonds, each with real material texture and motion blur.";
    transition-zone: "Sine wave ripples becoming actual horsehair strands. Fourier peaks morphing into anatomical cartilage.";
