/* ============================================================
 * PALETA — receita. (Barro + Fervura)
 * ------------------------------------------------------------
 * Barro   #8B4423  primária — nav, botões, ligações, estados activos
 * Fervura #D9A05B  acento — só como *fundo* ou marca gráfica.
 *                  NUNCA como texto sobre papel (2:1); sobre Barro, sim.
 * Filete  #A62A3A  o sinal da família — usar pouco, aparecer sempre
 *                  (barra 60×6, pontos finais, sublinhados de secção)
 * Papel   #EFEBE0 / Papel claro #F6F3EC / Papel Barro #F0E5DA
 * Tinta   #0F1922  texto; Marginal #6D7580 texto secundário (4.6:1)
 *
 * Cantos rectos em todo o sistema (--r-sm/--r-md = 0). Excepções redondas:
 * .pill, .suggest-pill, .tool-pill, .avatar, .m-spinner, .btn-icon,
 * .ai-input .send, .ai-fab, e os pontos decorativos.
 *
 * Três tipos, nada mais: Instrument Serif (títulos), IBM Plex Sans (corpo),
 * IBM Plex Mono (rótulos, botões, meta). Nenhuma cor fora do bloco :root.
 * O card-assinatura .receita-card vive em receita-brand.css.
