/*
 * x402.css: styles for the x402 browser client (x402-paywall.js). Served by the engine at
 * /_content/X402.AspNetCore/x402.css. The client injects no CSS of its own (build sheet 3.3), so a page that uses
 * the client links this file, or its own styles for the same classes.
 *
 * Theming: override the --x402-* custom properties (for example in the host's tokens). Fonts are the host's
 * business: the client uses --x402-font, which inherits the page's font unless a host sets it.
 * Mounted elements carry data-x402-state (loading | paid | payment-required | sign-in-required | forbidden |
 * not-found | unavailable | error), so every state can be styled from CSS.
