/*
 * Multi-Tool App Styles
 * 
 * HOW TO ADD A NEW THEME:
 * 
 * 1. In this file (styles.css):
 *    - Copy one of the existing theme blocks (e.g., body.theme-dark)
 *    - Rename it to body.theme-yourthemename
 *    - Customize the CSS variable colors
 * 
 * 2. In script.js:
 *    - Add your theme to the AVAILABLE_THEMES array:
 *      { id: 'yourthemename', name: 'Your Theme Name', icon: '🎨' }
 * 
 * That's it! The theme will automatically appear in the theme switcher.
 * 
 * CSS Variables used in themes:
 * --bg-primary: Main background color
 * --bg-secondary: Secondary background (lighter/darker than primary)
 * --bg-card: Card/modal background
 * --text-primary: Main text color
 * --text-secondary: Secondary/muted text color
 * --accent-primary: Primary accent color (buttons, highlights)
 * --accent-secondary: Secondary accent color
 * --border-color: Border colors
 * --input-bg: Input field backgrounds
 * --shadow: Box shadow color (with opacity)
 * --variable-bg: Variable tag background
 * --variable-color: Variable tag text color
