/* ARTEMIS Design System (baseline, hardening phase)
   - Tokens: colors, typography, spacing, radius, shadows, blur, motion.
   - Core patterns: .glass-panel / .ui-button / .ui-badge / .form-field / .status-block.
   - States matrix: default, :hover, :active, .is-selected, :focus-visible, [disabled],
     .is-loading, .is-success, .is-warning, .is-error.
   - Usage: prefer tokens and shared helpers over one-off values to preserve visual consistency.
