/* Radar da Enfermagem — folha de estilo única do site institucional.
 *
 * Regras deste arquivo:
 *   1. Toda cor vem de config/brand.yaml (fonte única de verdade da marca).
 *      Não existe hex inventado aqui: o teste tests/site/test_site.py lê o YAML
 *      e falha se qualquer token divergir do CSS. A chave `deep_green` do YAML
 *      aparece como `--deep-green` porque custom property não usa underscore.
 *   2. Nenhuma requisição externa: nenhuma hospedagem de asset, nenhuma web
 *      font. A tipografia é a pilha do sistema, portanto o primeiro pixel não
 *      espera a rede (e o teste proíbe até o nome de um provedor no arquivo).
 *   3. Nenhuma cor translúcida derivada (alfa em cima de um token): contraste
 *      previsível e rastreável até a cor aprovada.
 *   4. Três modos editoriais do design spec §4.3: Radar Editorial (navy/white/
 *      turquoise/red), Pulso Vivo (lime/deep-green/coral) e Plantão Impacto
 *      (yellow/black/white).
