/// Parser for [V4+ Styles] section content
///
/// Parses format definitions and style entries from the styles section.
/// Uses format mapping to handle different field orderings and missing fields.
///
/// # Performance
///
/// - Time complexity: O(n * m) for n styles and m fields per style
/// - Memory: Zero allocations via lifetime-generic spans
/// - Target: <1ms for typical style sections with 50 styles
