/**

 * EU Space Programme Visualization Component
 *
 * Mobile-first responsive styles for the interactive visualization.
 * Uses theme CSS custom properties where possible (--eusp-color-*).
 * For rgba() with transparency, colors are documented to map to theme tokens.
 *
 * Theme color reference:
 * - primary-500: #4a2bd6 = rgb(74, 43, 214)
 * - primary-400: #4a2bd6 = rgb(74, 43, 214)
 * - grey-80: #2a293b = rgb(42, 41, 59)
 * - grey-40: #dee2e6 = rgb(222, 226, 230)
 * - white: #fff = rgb(255, 255, 255)
 *
 * Breakpoints:
 * - Mobile: < 768px (default)
 * - Tablet: 768px - 799px
 * - Desktop: 800px+
