//! Gap Parser for Tailwind CSS
//!
//! This module handles parsing of gap-related utilities:
//! - Gap (gap-*)
//! - Column gap (gap-x-*)
//! - Row gap (gap-y-*)
//! - Space utilities (space-x-*, space-y-*)
//! - Space reverse utilities (space-x-reverse, space-y-reverse)
//! - Arbitrary space utilities (space-x-[...], space-y-[...])
