/*
 * CSS NAMING CONVENTIONS
 * 
 * 1. Module-prefix pattern: .module-element or #module-element
 *    - Example: .scroll-loading, .scroll-spinner, #scroll-trigger
 *    - Avoid generic names like .loading-indicator or .spinner
 * 
 * 2. CSS Custom Properties (Variables)
 *    - All colors and reusable values in :root
 *    - Example: --color-primary, --color-bg, --max-width
 * 
 * 3. Naming style: kebab-case only (no camelCase or snake_case)
 * 
 * 4. Semantic naming: reflect purpose and module ownership
 *    - Good: .scroll-loading, .post-header, .ticker-track
 *    - Bad: .blue-box, .big-text, .container-1
