/**
 * Main Header - Application main header component
 *
 * Note: Uses @size-* tokens for spacing and @headerHeight for calculations.
 *
 * Intentionally hardcoded values:
 * - Off-token spacing (9px, 11px, 15px): Legacy spacing not in token system
 * - Border widths (1px, 2px): Standard borders
 * - Percentages (50%, 100%): Layout
 * - Calc expressions: Complex computed values
 * - Transition durations: Animation timing
 * - Box-shadow values: Elevation
 * - Z-index values: Stacking order
