/* ============================================================
   H-008 (HUD Audit 2026-06-05, claude - ui):
   Antes os botões "Útil/Não útil" na statusbar tinham border e
   background transparentes → apareciam como texto puro, sem
   affordance de clique. Usuário leigo nunca percebia que era
   widget de retorno (RLHF signal perdido).
   Fix: pílula sutil visível + setas ↑/↓ via ::before + hover
   com cores semânticas (verde/vermelho) + estado persistente
   após voto. Nielsen H6 Recognition + WCAG 4.1.2 Name/Role/Value.
