/**
 * @file
 * AI Tools Library styles with support for Claro, Gin light, and Gin dark themes.
 *
 * This file uses CSS custom properties with a fallback chain:
 * 1. Gin-specific variables (--gin-*)
 * 2. Drupal core/Claro variables (--color-*)
 * 3. Hardcoded fallback values
 *
 * This approach ensures the Tool Explorer renders correctly in:
 * - Claro admin theme
 * - Gin admin theme (light mode)
 * - Gin admin theme (dark mode)
