This commit introduces a major internal refactor of the theme, replacing all dynamic styling mechanisms with a fully static, CSS-based system. The previous implementation relied on WordPress Customizer settings, PHP-based style generation, and inline CSS injection for fonts, colors, and header behavior. These systems have been completely removed and replaced with a deterministic architecture using CSS variables and dedicated stylesheets. Key changes: - Removed dynamic font system (Google/local/inline CSS) - Removed dynamic color system and Customizer controls - Removed legacy compatibility layer (legacy-aliases.php) - Removed custom header support and related UI (header image, text color) - Eliminated inline <style> injection in wp_head - Introduced static typography system via fonts.css - Introduced static color system via colors.css - Refactored style.css to rely entirely on CSS variables - Cleaned up conflicting font declarations and redundant rules - Simplified theme structure and reduced PHP overhead - Aligned translation template with theme slug (zeitfresser.pot) Result: - Improved frontend performance and caching behavior - Reduced PHP execution and complexity - Fully deterministic rendering without runtime style mutations - Cleaner, more maintainable codebase No visual changes intended.
