/**
 * Top Drawer - Collapsible top navigation panel
 *
 * Note: Uses design tokens for spacing (@size-*), colors, and layout vars.
 *
 * Intentionally hardcoded values:
 * - Layout calc expressions (76px, 72px, 56px, etc.): Header height combinations
 * - Specific widths (170px, 273px, 272px): Drawer panel widths
 * - Heights (380px, 445px, 220px): Drawer content dimensions
 * - 6px, 12px: Off-grid positioning adjustments
 * - 10000px, 2000px: Large clip values for overflow management
 * - Transition duration (0.35s): Animation timing
 * - Z-index calculations: Stacking order
 * - 1px borders: Standard border widths
 * - 100vw/100vh: Full viewport dimensions
