   MATERA CONSULTORIA EM TI — DESIGN SYSTEM (CSS de produção)
   Fonte: "Matera Consultoria Design System" no Claude Design
   (projeto d21edc53-e899-484c-a03a-5de41d3540c4), derivado do brandbook.
   Tokens copiados sem alteração; os componentes React do design system
   (Button, Card, Badge, SectionHeading, FeatureItem, Quote, Input, Select,
   Choice, Switch) viraram classes .m-* com os mesmos valores.
   Não inventar cor, não usar gradiente decorativo, não arredondar cantos.
