/* ── cd-states.css · estados vazios / loading / erro (redesign §2) ──
   4 padrões reusáveis medidos de screen-estados.jsx. Regra de ouro: todo estado
   vazio = ícone + título curto + 1 frase honesta (voz FIN) + 1 ação. Nunca "0"
   sozinho, nunca número inventado. Loading = skeleton (nunca spinner).
   Tokens via var(). Acento por instância via --es-accent (default = primary). */
