// Macros for theme definition and registration
//
// These macros reduce boilerplate when defining themes by generating
// the standard theme function from a color palette.

/// Macro to define a theme from a color palette.
/// Generates the `pub fn theme() -> Theme` function.
///
/// # Example
/// ```ignore
/// define_theme! {
///     bg: (0x28, 0x2a, 0x36),
///     bg_alt: (0x1E, 0x20, 0x29),
///     fg: (0xf8, 0xf8, 0xf2),
///     fg_alt: (0x62, 0x72, 0xa4),
///     base4: (0x56, 0x57, 0x61),
///     red: (0xff, 0x55, 0x55),
///     orange: (0xff, 0xb8, 0x6c),
///     yellow: (0xf1, 0xfa, 0x8c),
///     green: (0x50, 0xfa, 0x7b),
