…and theme system Major architectural improvements: - OKLCH color foundation with separate lightness/chroma/hue variables - Semantic alias layer (success, danger, warning, info) alongside priority names - Theme system supporting multiple named themes (enchanted-forest, ocean-breeze, etc.) - Automatic dark mode support via prefers-color-scheme - Layer-based CSS architecture for organized customization - Comprehensive README documentation Breaking changes: - Removed legacy token.css from default imports (still available in dual layer) - Converted color_token.css to user customization layer All existing functionality maintained: - Priority-based naming (Primary→Denary) - 5-color and 10-color modes - All color variations (tints, shades, highlights) - Component color system - Visual harmony over logical order philosophy Co-Authored-By: jesco@rpdevstudios.com <jglover88@hotmail.com>

Root cause: CSS layer cascade prevented dark mode from working. The dark mode rules in the 'base' layer were being overridden by higher-priority layers (themes, semantic-aliases, override). Solution: Moved dark mode rules from token_oklch.css to unlayered CSS at the end of site.css, giving them the highest priority in the cascade. Changes: - Added unlayered dark mode rules to site.css for both automatic (OS preference) and manual (data-color-scheme attribute) dark mode - Removed non-functional layered dark mode rules from token_oklch.css - Updated README.md with comprehensive dark mode documentation including JavaScript toggle examples Dark mode now correctly: - Inverts OKLCH lightness values (e.g., 35% -> 65%) - Redefines color variables inside media query and attribute selector - Preserves hue and chroma for harmonious color relationships - Supports both automatic detection and manual override Tested and verified working in browser with visual confirmation.

ZephyrCSS v2.0: OKLCH Architecture + Functional Dark Mode
Summary
This PR transforms ZephyrCSS from a hex-based color system to a modern OKLCH-based architecture while maintaining full backward compatibility. The major enhancement is fixing the broken dark mode that was previously non-functional due to CSS layer cascade issues.
Key Architectural Changes

Root Cause: Dark mode rules were in the
baseCSS layer and being overridden by higher-priority layers (themes,semantic-aliases,override).Solution: Moved dark mode rules to unlayered CSS at the end of
site.cssfor highest cascade priority. Now both automatic (prefers-color-scheme: dark) and manual (data-color-scheme="dark") dark mode work correctly.Review & Testing Checklist for Human
