/**
 * C8Y Child Assets Selector - Multi-select dropdown for child assets
 *
 * Note: Uses @size-* tokens; @form-control-* variables for styling.
 *
 * Intentionally hardcoded values:
 * - Off-token spacing (5px, 12px, 30px): Padding and margins not in token system
 * - Component-specific dimensions (240px, 278px): Dropdown dimensions
 * - Typography sizes (12px, 18px): Font sizes
 * - Percentages (50%, 100%): Layout and positioning
 * - Transition duration (0.15s): Animation timing
 * - Opacity values: Visual states
