//! Parked "controlled knob" highlighting code.
//!
//! This example's game loop used to paint two knobs green to show which
//! params a joystick was driving in the retired standalone C6 app. This crate
//! has no joystick, so the highlighting was always static and never toggled —
//! it was removed from
//! `armatron/main.rs` to stop the yellow-vs-green distinction from implying
//! knobs are interactive/ignored based on joystick state that doesn't exist
//! here. Kept in case a future input source (joystick, encoder, etc.) wants
//! the same highlighting.
//!
//! To restore: reintroduce a `controlled_knobs: [ControlledKnob; 2]` value
//! threaded through `armatron`'s loop and `draw_sliders`, and swap the plain
//! `fill_style(Rgb888::CSS_YELLOW)` knob draws back to
//! `knob_fill_style(&controlled_knobs, ControlledKnob::Param(...))`.
