/* ============================================================
   App Ora — folha de estilo da landing (redesign CLARO, 2026).
   Direção: SaaS claro e premium — fundo quase-branco, muito respiro,
   cards brancos com cantos generosos e sombra suave. Um acento de
   marca (teal petróleo da App Ora) carrega os botões e destaques, com
   um toque quente (âmbar) para os pontos de energia — no espírito das
   landings modernas de produto. Tipografia: Archivo pro texto e
   títulos, JetBrains Mono pros números e rótulos técnicos (preços,
   leituras de sinal, contadores).
