//! Scalar Field Dashboard - A living system monitor where UI emerges from chaos.
//!
//! The plasma field isn't decoration—it's the system's energy substrate.
//! UI panels react to the underlying field, creating a terminal that feels sentient.
//!
//! Controls:
//! - q/Esc: Quit
//! - r: Restart boot sequence
//! - Space: Pause/resume field animation
