/* preset-carbono.css — Carbono: PRETO e PRATA (verde só como destaque).
 * Construção: cópia da estrutura do tema ardósia ([data-nx-theme="dark"] em tokens.css) com as primárias trocadas —
 * ardósia (azulado) → carbono (neutro); neon → verde #A1C84D. Mesmas relações: canvas escuro que degrada para prata
 * (como o creme degrada para o amarelo-ovo), cartões prata-claro com texto escuro, "strong" preto com texto claro,
 * controles prata, hachura cinza. Fonte: a do sistema (não troca). Vale para os dois quadros (light/dark).
 * Contraste medido (WCAG): forense/CONTRASTE-CARBONO.md. */
