/**
 * Asset Property List - Tree view component for asset properties
 *
 * Note: Uses @size-* tokens for spacing and @size-base for calculations.
 *
 * Intentionally hardcoded values:
 * - Off-token spacing (6px, 7px, 14px, 18px, 42px, 44px, 96px): Tree indentation and positioning not in token system
 * - Border widths (1px): Standard borders
 * - Percentages (50%, 100%): Layout and positioning
 * - Font size (0.7em): Relative size for drag handle
 * - Transition duration (0.15s): Animation timing
 * - Calc expressions: Complex computed values for tree structure
