UX/variability win — collapse the expert knob-soup into one control plus a
legible summary.
- Variability macro (Chill/Spicy/Chaos presets + 0..1 slider) orchestrates the
stochastic knobs: eta (video variability), eta_final (late-noise ramp, only at
high chaos), quality_sharpness (detail recovery as noise rises), velocity spice
(action injection past Spicy, source=nearest), and motion pulses. Deliberately
keeps high_quality_pct>0 (disabling the deterministic finisher under ancestral
noise = mess). Writes the existing hybrid fields; all still individually editable.
- 'Active features (this config)' readout: green/grey rows for ancestral noise,
velocity spice, rescue, quality pass, motion pulses — turns the invisible stack
legible. Notes audio is auto-held deterministic on LTXAV.
Frontend-only; no model/Python changes (all fields already plumb through).
