//! Mnemonic normalization utilities.

/// Normalizes a mnemonic string by replacing commas or multiple whitespace with single spaces.
///
/// This handles various input formats:
/// - Comma-separated words: "word1,word2,word3"
/// - Whitespace-separated words: "word1  word2\tword3"
/// - Mixed separators: "word1, word2  word3"
///
/// # Examples
/// ```
/// use mx_core::normalize_mnemonic;
///
/// let mnemonic = "abandon,abandon abandon  about";
/// assert_eq!(normalize_mnemonic(mnemonic), "abandon abandon abandon about");
/// ```
