//! # Built-in themes
//!
//! **Purpose:** ship two themes that work out of the box.
//!
//! **Responsibility:** hold the palettes and assemble them into [`Theme`]
//! values. Only this module contains literal colours — everywhere else asks the
//! theme for a slot.
//!
//! Both palettes use 24-bit RGB. Terminals without truecolor degrade these to
//! the nearest colour themselves, which looks better than hand-picking ANSI
//! indices that clash with the user's own palette.
//!
//! **Public API:** [`dark`], [`light`].
//!
//! The light palette is not the dark one inverted: readable light themes need
//! *darker*, more saturated accents, because a pastel that reads well on black
//! disappears on white.
