//! Central color theme for the TUI.
//!
//! Flow: defines a single `Theme` marker struct with associated `Color`
//! consts, consumed by every `view/*` render function so styling stays
//! consistent and changeable from one place.
//!
//! Why: a zero-sized struct with associated consts (rather than an enum
//! or a runtime-configured palette) keeps color lookups compile-time
//! constant and allocation-free.

use ratatui::style::Color;

/// Central palette of terminal colors used across all TUI render functions.
///
/// Why: a zero-sized marker struct holding only associated consts, so
/// every view module references colors as `Theme::NAME` instead of
/// hardcoding `ratatui::style::Color` values inline.
