/**
 * ═══════════════════════════════════════════════════════════════════
 *  eKYC — SHARED DESIGN SYSTEM
 * ═══════════════════════════════════════════════════════════════════
 *
 *  This stylesheet defines the shared design tokens, base styles,
 *  and reusable components used across ALL eKYC pages.
 *
 *  THEME: "Forest Wellness" — bright natural greens, Figtree typeface.
 *  ("Metsakuur" means "forest cure" in Estonian.)
 *
 *  FOR DEVELOPERS — RE-THEMING:
 *    To re-theme the entire UI, override the CSS custom properties
 *    in the :root block below. All components reference these tokens,
 *    so changing them here propagates everywhere.
 *
 *  STRUCTURE:
 *    1. Design tokens (colors, spacing, typography, shadows)
 *    2. Base / reset styles
 *    3. Header component
 *    4. Phase tag (step indicator)
 *    5. Card / Panel containers
 *    6. Button variants (primary, secondary, ghost)
 *    7. Badge component (success / fail)
 *    8. Data grid (dt/dd key-value pairs)
 *    9. Spinner animation
 *   10. Scrollbar & focus styles
 * ═══════════════════════════════════════════════════════════════════
