/**
 * ManaVault - UI Polish Layer (v1.0.0)
 * (c) 2024-2026 BTCin Corporate s.r.o.
 *
 * CSS-only improvements loaded LAST.
 * Safe to remove: just delete the <link> tag to revert everything.
 *
 * Fixes:
 *  1. Missing definitions (modal-footer, form-control)
 *  2. Duplicate conflicts (btn-sm, btn-secondary)
 *  3. Transitions on all interactive elements
 *  4. Focus rings for keyboard navigation
 *  5. Modal backdrop blur + smooth animation
 *  6. Table polish (hover, zebra-striping)
 *  7. Dark-theme scrollbars
 *  8. Card hover consistency
 *  9. Badge utility classes (for future JS migration)
 * 10. Button consistency (success, warning padding)
 * 11. Disabled state clarity
