/*
 * ============================================================
 *  DESIGN SYSTEM — Trama (trama.work) — manual v3
 *  Tema claro: off-white, acento #B8F020, tipografia DM Serif / Sans / Mono
 * ============================================================
 *
 *  Mapa (manual): White #FFF · Off #F6F5F2 · g100 #EDECE8 · g200 #DDDBD4
 *  Texto g900 #1A1917 · g600 #5C5A55 · g400 #9E9B93
 *  Verde Green #B8F020 · Dark #6B9200 · ink #243200 · BG soft #EFF9D0
 *  Roxo: metadata apenas (#C4B3EE / #5236B8 / #EEEAFC)
 *  Dark UI (relatório): #151513 · #1E1E1C · borda #2E2E2C
 *
 *  EQUILÍBRIO 60 / 30 / 10 (páginas marketing claras):
 *    60% branco — #FFFFFF e #F6F5F2 (base, maior área, respiro)
 *    30% preto — texto #1A1917 + blocos escuros #151513 / #1E1E1C (tipografia, nav, secções dark)
 *    10% verde — #B8F020 e derivados (CTA, acentos pontuais; não diluir em grandes superfícies)
 *  Relatório HTML (tema escuro) não segue esta proporção literal — ver manual.
 *
 *  ANTI-PADRÕES:
 *    ✗  Não use cores hardcoded em HTML/CSS de páginas
 *    ✗  Não duplique tokens — crie aliases
 *    ✓  Só use variáveis --ds-* fora deste arquivo
 * ============================================================
