/* ============================================================ n4n · COMPONENT CSS — plain-CSS build of the primitives for non-React surfaces (Go templates, htmx, static HTML). Link styles.css FIRST (tokens + fonts), then this file. The design source is the app.n4n.ai console (n4n.ai/app); values mirror its Tailwind markup 1:1. Dark theme follows the token remap ( or ). Use this when porting n4n.pay / pay-admin / the IdP. ============================================================ */ /* ---- Card: flat white, zinc hairline, rounded-xl, no shadow ---- */ .n-card { padding: 16px;
