/**
 * Card - Base card component with all variants
 *
 * Note: Uses @size-* tokens extensively; @font-size-* tokens, and component variables.
 *
 * Intentionally hardcoded values:
 * - Component-specific dimensions (56px, 60px, 66px, 80px, 90px, 100px, 140px): Card sizes and minimums
 * - Typography sizes (18px, 20px, 22px, 36px): Icon and heading font sizes
 * - Border widths (1px, 2px): Standard borders and outlines
 * - Negative offsets (-1px, -2px): Fine-tuning
 * - Percentages (100%): Layout
 * - Z-index values: Stacking order
 * - Opacity values: Visual states
 * - Transition durations: Animation timing
 * - Box-shadow values: Elevation effects
 * - RGBA values: Transparency
