/**
 * Common CSS - Base structural styles shared across all pages
 *
 * This file defines foundational classes for consistent UI components:
 * - Section containers (card-like boxes)
 * - Table wrappers
 * - Stats badges
 * - Flex layouts
 * - Filters sections
 * - Table toolbars
 *
 * Themes can override these by:
 * 1. Redefining the CSS variables (--common-*)
 * 2. Overriding the classes directly (theme CSS loads after this)
 *
 * Load order: Bootstrap -> common.css -> theme CSS
