Dropped the internal waveform lines — not what we wanted visually —
and replaced them with a spectrum-driven deformation of the sphere
outline itself. Each of the 12 log-spaced bands drives one Fourier
mode of the perimeter (band b → mode b + 2, so modes 0/1 stay
circular and higher bands produce tighter ripples). Low bands pull
the shape into wide asymmetric bumps that feel like formants; high
bands add quick sibilant-like tremors. Phase advances faster for
higher modes so tight ripples visually match high-frequency content.
Overall displacement is gated by the RMS envelope so silence is
quiet and loud syllables distort strongly. Fill + highlight are
clipped to the deformed path so the gradient follows the shape and
it reads as a single living object rather than a circle with stuff
bolted on.
Removed drawSpectrumBars and drawWaveformLine.
