/* ============================================================================
   Desync brand components — ported from brand-demo-draft-6.html, cleaned.
   Changes vs source:
     · added .btn-error / .chip-error / .alert-* using --rubric
     · fixed the `chip chip` duplicate-class typo -> real tier modifiers
     · icon selectors retargeted from [data-lucide] spans to the <svg>
       that leptos_icons emits
