AI ASSISTANT — MAJOR UPGRADE • Upgraded to faster, more reliable AI (Gemini 2.0 Flash) with automatic retry when the service is busy. • Describe your goal in plain English — the guide now configures engine mode, frequencies (0.1–500 Hz), carrier, phase, stereo drift, noise layers, and timed sequences. • Simple Mode Home: one combined AI box for guidance and sequences; voice input auto-submits when you finish speaking. • Tap any past AI reply to re-apply that session instantly. • Built-in rate limiting with a clear cooldown so the service stays responsive for everyone. • More accurate handling of Epsilon, Lambda, and the full premium band range — no more silent wrong defaults.
