//! egui styling for the control panel. Deep-space cyan/orange theme,

//! Pinned to egui 0.35: the `Shadow` struct packs fields into 8-bit integers,

//! and the context style API is `set_theme` + `global_style_mut` (not the

//! `ctx.style()`/`set_style()` of 0.34). See inline comments at each site.
