/**
 * Books Color System
 * 
 * Standardized color references for each book in the Reverie House library.
 * These CSS variables define color palettes for book-specific styling.
 * 
 * Each book has:
 * - Primary color (main brand color)
 * - Secondary color (complementary accent)
 * - Background color (page/card backgrounds)
 * - Text color (readable text on backgrounds)
 * - Light/medium/dark variants for flexible theming
